We’re excited to announce our Engine Control Unit (ECU) Upgrades the Audi RS5 (B9) 2.9 TFSI engine now includes APR Plus! APR Plus combines our ECU Upgrade with a factory term matching limited powertrain warranty! Expect massive gains with 488 HP and 537 FT-LBS of torque on tap from this simple software upgrade.


Our new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We’ve extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team’s pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After track days, acceleration tests, and dyno sessions, we created new calibrations that are fine tuned for several octanes, including ethanol, and contain hundreds of map changes, with a vast array of safety features built in.
