APR ECU Explorer:
APR’s proprietary ECU Explorer gives APR’s Calibration Engineers unparalleled access to the vehicle’s entire engine management system. Typical commercially available data logging tools, used by most tuners, only allow logging up to 12 engine-operating variables at extremely low data rates. These tools are also limited to a small, specific list of variables. APR’s ECU Explorer is capable of logging every variable found within the ECU. It’s capable of logging well over 100 variables at once with data rates as high as 100 samples per second. Synchronous data logging is available for fine-tuning.
![]()
APR ECU Composer:
APR’s proprietary ECU Composer is used for altering the engine management system. With full access to every table, map and variable within the ECU, APR’s Calibration Engineers are not limited to a handful of maps as is common for most tuning companies. ECU Composer takes calibration to a new level on the 3.0T FSI with APR’s Quick Flashing. APR’s Calibration Engineers can reflash the ECU only a minute later rather than waiting 10 to 20 minutes between each flash.
![]()
APR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU to add features not available from the factory. Through code levels changes, APR’s Engineers are able to add features to the ECU. Other changes allow higher torque limit than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. This allows APR’s engineers to not require DSG software to meet or exceed advertised gains. On the highly modified end, this allows APR to make Stage III Turbo Upgrades operate as if intended by the OEM. For most 3.0T owners, the advantage of this ability is the addition of APR’s patented EMCS Functions. EMCS puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to your ECU.

APR Oil Protection System (OPS)
Written by dion on June 3, 2013 – 12:00 pm -
Achtuning is pleased to announce APR’s release of their Oil Protection System (OPS) for the 2.0 TSI EA888 Gen 1 engine. The OPS is designed to protect the engine from oil starvation, which can cause immediate and comprehensive engine failure.
The APR OPS is a racing inspired product backed by years of testing in the Grand-AM Continental Tire Sports Car Challenge. APR Motorsport’s 2.0 TSI racing program quickly exposed issues related to the engine’s design, leading to rapid engine failure during high lateral G loads. These situations are easily producible on the street during spirited runs on a twisty road, or taking highway on-ramps at high speeds. However, they are exacerbated on the track with race compound tires.
The TSI’s oil starvation problems are caused by the engine’s inability to circulate oil back to the oil pan and pickup point quickly enough during the driving situations described above. The oil level in the pan falls below the pickup point and oil pressure drops. With oil no longer providing a protective barrier between critical components, metal on metal contact occurs, wearing parts rapidly. With enough wear, massive engine failure can occur.
APR Motorsport spent a considerable amount of time researching the TSI’s oiling system to investigate traditional methods of addressing the problem. Baffling the oil pan, modifying the PCV system and enlarging the drain back ports from the cylinder head proved ineffective. Once the problem was fully understood the APR Oil Protection System (OPS) was created.

The OPS is a pressurized external oil accumulator designed to instantly add oil into the system the moment oil pressure dips below a predefined level. The OPS slowly presses oil into the system over a period of time until pressure equalizes, and starvation is no longer an issue. The included APR CAN Controller interacts with the ECU on the CAN bus allowing APR’s engineers to calibrate the system to only activate when necessary. At a specific RPM, the system automatically arms. This prevents the OPS from over filling the engine while idling in the pits at the track or while stopped on the street.

Audi TT: New Lease On Life
Written by dion on May 31, 2013 – 11:15 am -
Troy brought us his 2001 Audi TT that he and his family have daily driven since the car rolled off the dealer lot 12-years ago. Regular service intervals and all-around proper care kept this 150K mile roadster in great shape and has served the family well. Not yet willing to part with the car after picking up a new Audi TTRS, Troy decided to bring their beloved TT to Achtuning for a new lease on life. It was decided the TT would serve as the family’s weekend fun-mobile and eventually a dedicated track car so engine, suspension, and brakes would need attention. For phase 1 of the project we inspected the car completely and found a few items needed to be addressed before adding more go-fast bits. Once that was all done, we moved on to phase 2 with suspension and brakes. First, H&R’s Street Performance Coil-Overs would replace the TT’s original and now very worn suspension and allow the TT to corner with ease and keep the car stable. StopTech’s ST40 355mm big brake kit would serve to better stop the TT before we add more power while the popular motorsport inspired Hartmann Euromesh 4-GS wheels were mounted to clear the new, much larger brake calipers.

Phase 3 will begin in a week or so with a Techtonics Tuning down-pipe mated to a Hartmann cat-back exhaust which will complement the APR K04 turbo that will make it’s way under the hood. Stay tuned!

APR 2.0T FSI Stage III GTX Turbocharger System & Upgrade Kit! (EA113-K03 Vehicles)
Written by dion on May 14, 2013 – 2:40 pm -Achtuning presents the APR 2.0T FSI Stage III GTX Turbocharger System & Upgrade Kit! (EA113-K03 Vehicles)

Building upon over a decade’s worth of experience with turbocharged Audi and VW engines, including over half a decade with direct injected engines, APR’s Engineers have taken the 2.0T FSI to ground breaking levels of performance without compromise.
APR has introduced the 2.0T FSI Stage III GTX Turbocharger System. Producing over 405 horsepower on 93 (R+M)/2 octane and 449 HP in racing configurations, Stage III GTX places the 2.0T FSI’s accelerative performance in the same league as that of large V8 supercharged muscle cars and sub $400,000 exotic sports cars.
The new APR Stage III GTX Turbocharger System represents a large leap in technology over our previously available GT Turbocharger System. The new system’s response is much quicker, spooling hundreds of RPM sooner thanks to the latest in Garrett turbocharger technology and advancements in the ECU Upgrade. Further refinement of the fueling system increases the vehicle’s reliability and drivability to levels only matched by the OEM. A substantial increase in horsepower and torque results in roughly a 30-50 HP gain in the area under the curve over the previous system. As you hear a new exotic growl from your exhaust system, expect exhilarating g-force levels sure to put a huge grin on your face!
To learn about many component included in the APR Stage III GTX Turbocharger System, see below. For previous owners of the older APR Stage III GT Turbocharger System, an upgrade package is available.
APR Stage III GTX Components
Turbocharger
At the heart of Stage III GTX is a GTX2867R turbocharger, consisting of the latest technologies from Le Mans’ winning turbo manufacturer, Garrett Honeywell. The internally gated unit features a fully-machined, ten-blade billet compressor wheel and a dual ball bearing oil and water-cooled CHRA. APR’s Engineers spent countless hours testing turbine inlet and A/R sizes in order to decrease turbocharger lag without negatively impacting peak power. The newly developed compressor housing utilizes anti-surge porting, which greatly complements the lightning fast spool characteristics of this unit and grants APR’s Engineers the ability to deliver massive levels of torque inducing boost pressure, even in the lower RPM range.
Each turbocharger unit is assembled and clocked in house at APR with the necessary brackets to ensure proper wastegate fitment and orientation. Each wastegate is then calibrated for precise operation and control to ensure seamless integration with the expertly recalibrated OEM engine management system.
APR Stage III GTX Software

The factory Bosch MED 9 engine management system is responsible for proper operation of the engine in all conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marks.
With the significant amount of changes included in the APR Stage III GTX Turbocharger System, APR’s Engineers spent months recalibrating the engine management system to operate smoothly as if intended by the OEM. Thanks to APR’s incredible proprietary calibration suite, data logging software and full access to the coding structure of the ECU, appropriate and intelligent changes are made to ensure flawless drivability and excellent performance without compromise.
APR’s EMCS program switching technology puts control of the ECU in your finger tips allowing you to access modes for standard pump fuel, high output race fuel and even reduced output valet modes to protect your vehicle against improper use by other individuals. This technology is patented by APR and is found nowhere else in the world. It’s Performance Without Compromise only APR can deliver!
*Note* Exiting APR Software customers will receive a fully loaded ECU. New Customers will receive 1 program and may purchase additional programs al la cart. Please check for EMCS availability.
Exhaust Manifold

Attached to the turbocharger is APR’s investment-cast, super alloy, nickel-chromium-based Inconel 625 Manifold featuring APR’s Sequential Exhaust Pulse runner lengths. Unlike hand welded tubular manifolds, Inconel is a very high temperature resistant material designed to withstand extreme exhaust gas temperature changes without expanding, contracting, melting or cracking under stress. This material is typically found only at the highest levels of professional motorsport racing where reliability is essential to success.
Investment-cast Inconel features heat retention characteristics which aid in turbo response by keeping exhaust velocity high. Ensuring each exhaust pulse arrives at the collection point without collision is critical to producing lightning fast response and immediate torque delivery. Using 3D modeling and computational fluid dynamics software, APR’s Engineers designed varying short runner lengths calibrated to deliver sequential exhaust pulses without collision. A reduction in backpressure from the high flow design directly enhances power delivery.
Each manifold is investment-cast in the United States of America and machined in house on APR’s CNC machines to ensure high casting tolerances, repeatable results and strict quality control. The thick casting material reduces unwanted exhaust noise leaving behind a powerful and exotic growl.
All of these characteristics result in a manifold designed without compromise backed by a confidence inspiring lifetime warranty.
Induction and Charge Piping

Wire reinforced, multi-ply silicone hoses provide an unrestricted path for airflow to enter and exit the turbocharger at over 1,000 kilograms per hour. The ultra rigid design ensures boost and vacuum piping will not swell or collapse causing leaks and restrictions in the induction and charge piping system supporting boost response and turbo recovery. Each hose is engineered to fit properly into the vehicle’s engine bay with all necessary emissions and reference ports securely affixed.

APR’s Easy-Flow Silicone Hose design features stepped mounting surfaces for smooth transitions from one pipe to another. Traditional designs simply sit on top of each other, often resulting in a disruptive airflow path. By using the stepped design, hoses fit properly without airflow restrictions, resulting in the most ideal path for moving air through the turbocharger and into the engine.
Turbo Outlet Pipe

To provide unrestricted and smooth airflow from the turbocharger to the intercooler, the APR Stage III GTX Turbocharger System includes a cast enlarged turbo outlet pipe to properly deliver the additional airflow from the larger turbocharger.
Mass Airflow Housing

The vehicle’s engine management relies on load calculations to accurately control the engine. Calculations are made by measuring airflow across the Mass Airflow Sensor and this is a critical component of the APR Stage III GTX Turbocharger System.
The small and restrictive factory unit is removed and replaced with the much larger housing. To ensure accuracy, APR’s MAF housing is cast in the United States of America and CNC machined in house at APR to ensure repeatable results. The long, precision-machined housing features a honeycomb airflow straightener to further aid in accurately reading airflow levels. Simply enlarging the MAF housing is not permissible without accurate adjustments to the factory engine management system, which is included with APR Stage III GTX Turbocharger System.
Oil and Coolant Lines

APR’s oil and coolant lines are specific to the vehicle’s Stage III GTX System and provide years of leak free operation. The oil lines feature flexible braided stainless steel with CNC mandrel bent hard-lines for specific and clean hose routing as if intended by the OEM.
Low Pressure Fuel Pump System

The APR Low Pressure Fuel Pump System is a complete, OEM style, PWM controlled drop in fuel pump and controller solution designed to fit cleanly in the OEM location. The upgraded pump provides adequate low-pressure fuel to the APR High Pressure Fuel Pump to support the power levels produced by the APR Stage III GTX Turbocharger System.
High Pressure Fuel Rail Valve

The factory vehicle’s gasoline direct injection injectors require higher than factory fuel rail pressure to achieve targeted air fuel ratios under high load, wide open throttle operation. APR’s Low Pressure Fuel Pump delivers the desired volume of fuel to the APR High Pressure Fuel Pump, which provides increased fueling headroom over the factory unit. However, the factory High Pressure Fuel Rail Valve limits maximum rail pressure below the desired level. The included APR High Pressure Fuel Rail Valve is calibrated to increase the maximum rail pressure to levels necessary for proper operation.
In doing so, APR’s able to support far higher horsepower levels than achievable on the existing APR Stage III GTX Turbocharger Systems without the need to alter the factory, correct spray pattern, injectors. This results in smoother part throttle operation, factory-like cold starts and fewer unburnt hydrocarbons emitted from the tailpipe under all conditions compared to other fueling options.
Cast Downturn and Downpipe

The GTX2867R internally gated turbocharger unit features a Garrett five-bolt flange, which differs from the OEM turbocharger flange. To support this design, the APR Stage III GTX Turbocharger System includes cast stainless steel exhaust downturn and downpipe, which mates directly to an APR Midpipe, Downpipe or Turboback Exhaust System.
Nuts, Bolts, Gaskets, Washers, Clamps, Fittings, etc

Every APR Stage III GTX Turbocharger System includes all necessary components for a complete install.
Bracketry

No matter how small the part, each piece of the APR Stage III GTX Turbocharger System oozes with quality evident in pieces like the Stage III GTX’s laser cut ancillary brackets and carriers.
Spark Plugs

Proper temperature range spark plugs are included with each APR Stage III GTX Turbocharger System.

Finding the Bottlenecks
In simplest terms, an engine is an air pump. The more air an engine can flow, the more power it can achieve given an adequate supply of fuel and ignition. Through development, APR has been able to continually increase power on the 2.0T FSI by finding bottlenecks in the system and eliminating them one at a time.
The 2.0T FSI’s factory intake and exhaust are the first two items causing an airflow restriction and as such both of these items are upgraded to expand the capabilities of the engine. After this, the factory K03 turbocharger becomes a restriction and therefore an entry level K04 Turbocharger System is available. This turbocharger comes standard on several high-end Audi, VW and Seat vehicles and eventually becomes the largest restriction point in the system.
APR’s solution to the flow-limited factory turbocharger is the Stage III Turbocharger System. Stage III consists of an entirely new high flow exhaust manifold, small frame Garrett Honeywell Turbocharger and larger turbocharger inlet and outlet plumbing. This system is capable of exploiting the bottleneck in the system between the K04 and Stage III, which in this case is the factory cylinder head.
As the final stage of the air intake and the first stage of the exhaust, the cylinder head is the most critical piece of the air pump. The cylinder head is a restriction on both the intake and exhaust side at Stage III airflow levels. This results in a relatively high boost-to-airflow ratio and excessive backpressure on the exhaust side. By machining the cylinder head ports, the boost-to-airflow ratio decreases by as much as 10% and enough backpressure is alleviated to extend the spark knock threshold by roughly 7 degrees. Together these benefits and others translate into an additional 70-126 HP, depending on octane, over our standard Stage III Turbocharger System!

Testing
APR has tested countless cylinder head port profiles over the past five years to ensure they’ve arrived at the best possible configuration. It’s important to understand that an increase in flow at the inlet or exhaust port is often coupled with a decrease in air velocity. Porting the cylinder head is not a simple process of making each port larger. For this reason, porting the cylinder head on a vehicle with a K04 or smaller turbocharger will actually decrease the output of the engine. The turbocharger itself represents a larger restriction than the cylinder head, so porting accomplishes nothing other than decreasing the velocity of the air as it enters the cylinder. In turn, this increases the time between spark and combustion making a slower burning, less powerful engine flowing no more air than it did before.
Through testing on APR’s Superflow Flow Bench, they’ve also discovered many different sizes and shapes would show no benefit in flow but would result in decreased velocity. As such, some ports may retain parts of their original casting, unmachined. This is not a mistake, as increasing the port size slightly larger to ensure all surfaces are machined proves less than ideal. CNC porting allows for precise profiling unachievable through hand porting and makes compensations necessary to account for core shift. The ultimate goal and end result was developing shape, volume and profile for each port that results in the highest flow yet the least decrease in velocity over stock.
APR’s Engineering Teams took development a step further though testing of 1mm oversized valves on both the intake and exhaust. Despite offering a significant improvement in airflow on the flow bench, there were no performance advantages from the engine. As mentioned earlier, the bottlenecks are located one at a time and between a ported head and oversized valve ported head, the restriction once again becomes the turbocharger system. The advantages of oversized ports are not realized until well over the 500 HP mark, which extends beyond other limitations in the system.
APR Stage III+
![]()
By purchasing an APR Stage III+ Cylinder Head, your existing APR Stage III Turbocharger System’s software will be upgraded to APR Stage III+ Software, free of charge.
You must own an APR Stage III or Stage III GTX Turbocharger System to qualify for the free software upgrade.
Ordering Process
The process is simple. We’ll ship APR your cylinder head. They’ll perform the work and ship it back.
![]()
Upon arrival each head will be inspected. If the head passes inspection, it will be disassembled, receive a thorough cleaning in APR’s Ultrasonic bath to remove carbon buildup, and finally ported on their in house CNC head-porting machine. After the porting process has been successfully completed, the head will undergo one final ultrasonic cleaning before being reassembled. The valves will be lapped and a final leak down test will be conducted, on APR’s purpose built test fixture, to ensure proper installation.
Requirements:
APR Stage III+ Software requires an APR Stage III or Stage III GTX Turbocharger System. Depending on which system or modifications you own, these components may not be necessary.
