The TT RS just got even more exciting. It was already an amazing value, with acceleration numbers near that of a V10 Audi R8. Those numbers just got a whole lot better with the introduction of APR’s ECU upgrade that increases power to up to 414 HP and 430 TQ! Here is the official press release. Needless to say we can’t wait to drive a TT RS with this upgrade. Be sure to visit APR’s product page for more information or to find a dealer near you. 

APR Presents: North American Audi TT RS 2.5 TFSI ECU Upgrade!

APR is pleased to present the ultimate ECU Upgrade for the Audi TT RS and 
RS3 2.5 TFSI. After months of long nights and many hours of testing, development 
and more testing, we are pleased to offer you an ECU recalibration that is 
second to none. APR’s extensive research and development provides you 
with a powerful ECU Upgrade with no loss of drivability or reliability. Expect 
tremendous increases in power and torque across the entire power band, 
improved throttle response and a smoother, more powerful top end.

The 2.5 TFSI’s engine management presented new challenges to the 
Engineering Teams at APR in the form of new control strategies for 
torque management. Significant time was spent researching these new 
strategies to properly request more load and therefore more boost in the 
lower end of the power band. The results were simple, a torque curve that 
crushes the competition and delivers a rush of power like no other in the industry.

The Audi 2.5 TFSI ECU Upgrade is an expertly recalibrated engine control 
strategy that remaps boost, timing, air fuel ratios and other engine 
management paramaters to provide smooth and reliable power as if intended 
by the OEM. APR’s ECU Upgrade is developed to work within the OEM 
and Tier 1 Supplier specifications for engine component stress tolerances 
and performance specifications. APR’s ECU Upgrades are available in 
octane specific versions to allow you to take full advantage of the fuel 
quality available in your area.

Stage I ECU Upgrade

Not only does our Stage I ECU Upgrade give you higher peak numbers of 
414 horsepower and 430 ft-lbs of torque, but also gains of up to 73 horsepower 
and 79 lb-ft are available at lower RPMs! APR’s ECU Upgrade is the best 
power per dollar modification for the new 2.5 TFSI and gives it just the extra 
edge these cars lack from the factory without pushing the limits. With factory 
like smoothness and drivability APR’s ECU Upgrade will fill the void in an 
otherwise excellent car.
