APR’s Engineering Team has finished final testing of a new ECU Calibration for APR’s 2.0 TSI Stage III Turbocharger Systems. The results are an additional 65 hp and 75 lb ft of torque. Simultaneously, APR presents a road course mode available through EMCS exclusively for the 2.0 TSI Stage III that provides a similar torque delivery profile to APR’s original ECU Calibration as included in the Stage III System.

APR has over 2 years of experience reaching the limits of the OEM internals through participation in the GRAND-AM Road Racing Series. Automotive Engineering firms have continuously turned to endurance racing as proving grounds for new technologies and to measure the durability and viability of these new technologies in a rigorous total system accelerated life-testing environment found in very few alternatives. Through this testing and research APR’s Engineering Team is able to deliver a more powerful application of the Stage III Turbocharger System and do so knowing little to no loss of life will be suffered in comparison to the Original Calibration and engine performance levels.

As APR’s Original Calibration was developed to help manage torque application in low traction situations, APR’s Engineering Team will offer 2.0 TSI Stage III owners the ability to use their OEM cruise control stalk to select a similar torque delivery profile to APR’s original ECU Calibration or the new Calibration power levels to best suit their driving situation in most currently available fuel quality specific calibrations. For the first time ever and only available to this application, APR introduces calibrations with drastically different power levels for the same fuel quality through EMCS.

Existing 2.0 TSI Stage III owners may come in for a free software update (excluding labor where applicable) to the new v2.0 ECU Calibration. Go APR!

Scott dropped off his Candy White Mk5 GTI with us yesterday. He will be the first of many Mk5 customers to receive the APR Stage 3 treatment from Achtuning.

The award winning APR 2.0T FSI Stage III delivers a powerful, refined, turn-key solution from the expertly re-calibrated engine management system to the investment cast inconel exhaust manifold and upgraded FSI fuel injectors and fuel pump. Featuring the APR/Garrett Honeywell Ballistic Series GT2871APR Ball Bearing Turbocharger, the APR Stage III brings your MkV to 382 daily drivable horsepower and 332 pound feet of neck snapping torque.

We laid out Scott’s parts for him as this will be the last time we expect him to see these individual components in their virgin form.

So we’ve begun installation, and plan to have things wrapped up within the next few days. Here are some current progress pictures of the installation. New injectors are already in, along with the high pressure FSI fuel pump. The stock high pressure pump is incapable of pumping a high enough volume of fuel to support the FSI engine with even moderate mods, much less a large turbo kit. To rectify this, APR has developed a higher flowing fuel pump that eliminates this being a problem.

We’ve already begun the intercooler portion of the install as well and we’ll update you with more progress as we get the opportunity. Scott, we have definitely passed the point of no return.
