We’re moving along as we’ve got the APR K04 turbo upgrade, turbo-back exhaust, and intercooler installed on Tim’s VW (Mk6) GTI today. APR’s ECU software upgrade specific to the K04 turbo is being loaded next to ensure proper management of the upgraded components and then we’ll tackle suspension and brakes in our next installment!

A recent post made by Arin@APR shows some incredible gains to be had with the B8-chassis Audi A4 when upgrading to “APR Stage 2″ using their new RSC free-flow exhaust system.  Still in development, but available to the public VERY soon…

The APR RSC Turboback Exhaust Systems were so free flowing the Engineers were able to make safe calibration changes which resulted in the following:

1. Significantly reduced turbocharger spool time over both stock software and APR stage 1 software.
On the days of testing, stage 1 torque levels at 2400 RPM’s were met and exceded at 2000 RPM’s (400 RPM’s Sooner!) simply by running APR stage 2 software with the RSC Turboback Exhaust System

2. Significantly increased and broadened the torque curve compared to both stock and APR stage 1 software.
-On the days of testing, stage 2 torque levels rose 89 FT-LBS under the curve compared to stock software. Peak torque rose from 267 ft-lbs to 355 ft-lbs, for a 88 FT-LBS peak increase.
-On the days of testing, stage 2 torque levels rose 66 FT-LBS under the curve compared to stage 1 software. Peak torque rose from 334 ft-lbs to 355 ft-lbs, for a 21 FT-LBS peak increase.

3. Significantly increased horsepower, especially the area under the curve compared to both stock and APR stage 1 software.
-On the days of testing, stage 2 torque levels rose 50 HP under the curve compared to stock software. Peak power rose from 212 hp to 248 hp, for a 36 hp peak increase.
-On the days of testing, stage 2 torque levels rose 27 HP under the curve compared to stage 1 software. Peak power rose from 235 hp to 248 hp, for a 13 hp peak increase.

All of our data was collected on back to back runs and are the results of average data. Data was also collected on the same car during several days of testing. Gains between runs were in some cases higher but we have chosen to show you an average of what you’ll expect to see as data can change between runs based on countless variables.

Now for the dyno charts of our development progress!

This Audi TT has received a couple upgrades from us already, but Rohit has caught the modding bug so it’s back to receive more of the “Achtuning” treatment courtesy of APR’s 3″ turbo-back exhaust. And what better time to take advantage of APR’s “Power Into Summer” sale pricing!

Higher flow means more power and a nice grumble, then accompanied with APR’s ECU software upgrades this once stock Audi TT with 225 hp is expected to see power figures closer to the 260 range. Not to mention the weight reduction dropping the heavy stock exhaust set-up.

We know Rohit will be back for more…

John’s Audi TT received a good deal of upgrades courtesy of an APR 3″ turbo-back exhaust and Stasis Streetsport suspension.

The turbo-back exhaust is a completely stainless-steel, mandrel-bent system that looks stunning beneath John’s car. At idle it has a nice low tone, deeper than stock. Once you hit the throttle though the car really makes its presence known.

We’ve got 20 VW Mk5 GTI RSC full exhaust systems (down-pipe/cat-back) on the shelf, ready to ship! Purchase an RSC exhaust system for your Mk5 GTI and I’ll ship it to you for FREE!!

Chris drove down from Vancouver, BC and left us his Audi B7 A4 to get some work done. Chris had us install the Stasis Streetsport Coil-Overs , APR Snub Mount , and APR turbo-back exhaust while taking in some of the local sights.

We hope to see Chris return later for some Hartmann Wheels to compliment his new stance – only time will tell!

Mark came in to see if we could do anything about his previous exhaust set-up – Apparently the down-pipe was bent after the car had bottomed-out. Ultimately it was determined that a replacement would be needed so Mark selected APR’s full system this time around.

It will be interesting to hear back from Mark about the differences (if any) between his previous exhaust (DeCorsa) and his new APR set-up.

This beautiful white B6 A4 was dropped off this morning to receive an APR turbo-back exhaust. APR’s full stainless-steel exhaust system is currently 15% off during our Achtoberfest Sale which put the price of the upgrade with installation just over the price of the exhaust at full price!

So first thing’s first, out with the old:

We all know the car already looks sharp, but the new 3.5″ rolled and stainless-steel exhaust tips help tie in the polished lips of her Lexion wheels, LED tails, and Audi trunk badge.

Thanks for the opportunity, Linds!
