$999.99

The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 459-542 HP with 451-506 FT-LBS of torque, depending on octane. Gains as high as 66-132 HP and 88-146 FT-LBS of torque are available throughout the power band. To get more power, the vehicle can be outfitted with an upgrade intake, APR RS3 Intercooler System or APR TTRS Intercooler System, catback exhaust and other small modifications without requiring any new modification to the ECU. Upgrading the small factory intercooler is highly recommended on this platform. 

APR "Lo Grip" Stage 1 modes are equipped with a feature that helps reduce wheel spin and aid in 60FT and 0-60 times on street tires and unprepped surfaces. However, for vehicles equipped with much better tires and surface prep, an optional "High-Grip" mode is available to maximize launching performance. 

APR Stage 1 is available for 91, 93, 100, 104, and E85 fuel grades in North America.

Please note, APR's E85 software is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump fuel or race fuels or use race specific barrels of E85. To ensure proper E85 content levels, APR recommends using an E85 content sensor.
