• 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. APRís 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 TFSIís 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. APRís ECU Upgrade is developed to work within the OEM
      and Tier 1 Supplier specifications for engine component stress tolerances
      and performance specifications. APRís 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! APRís 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 APRís ECU Upgrade will fill the void in an
      otherwise excellent car.
