APR releases Stage I ECU upgrade for the Audi TT-RS, hits 414 horsepower - $899

We really like the things APR does. One thing we do not like about them though is the dyno's that they post which show crank figures. Would it really kill them to show us the numbers at the wheels as it should be? Regardless, on 93 octane fuel their baseline horsepower number for the TT-RS is 375 and after the tune on the same fuel the number is 414. Torque figures are boosted from 365 to 430. This tune is available for all TT-RS models, North American cars need to send their ECU in.


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.
