APR is pleased to present the worlds first ECU Upgrade for the 3.0 TFSI engine. After almost a year of accelerated life testing through professional motorsport racing, 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 huge increases in top-end power, improved throttle response and a smoother, more powerful powerband.

The APR 3.0 TFSI ECU Upgrade is an expertly recalibrated engine control strategy that remaps the boost pressure, timing and air fuel ratios inside the factory ECU 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. APR's forthcoming patented EMCS functionality puts the control of the engine's operation at your finger tips and allows for additional features and options to be installed to your OEM ECU.

Not only does our Stage I ECU Upgrade give you higher peak numbers of 362 horsepower and 345-ft. of torque measured at all 4 wheels, but also gains of up to 77 all wheel horsepower and 57lb-ft are available throughout the power band! APR's ECU Upgrade is the best power per dollar modification for the new 3.0 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.
