About this app

The APR Power Control Unit (PCU) is an inline tuning box designed to increase the horsepower and torque of the vehicle! The plug-and-play control unit piggybacks off the primary Engine Control Unit (ECU) to deliver more boost, fuel, and timing to increase output. Using your smart phone or the optional wireless controller, you can change performance levels on the fly, revert to stock, adjust throttle sensitivity levels, read emissions readiness, read and clear fault codes, and more.
