APR ECU Upgrades for Porsche Cayenne GTS & GTS Coupe 4.0T

APR is excited to announce their Engine Control Unit (ECU) Upgrades are now available for the Porsche Cayenne GTS and Cayenne GTS Coupe (9Y) 4.0T engine with the Bosch MG1 ECU! Expect massive gains with up to 685-767 HP and 731-804 FT-LBS of torque on tap, depending on octane, from this
simple software upgrade.

Their new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Their upgrade makes the engine more powerful and more exciting. They’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 their engineering team’s pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with their high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning they created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.
