The APR Stage 1 ECU Upgrade is the first step towards making more power! The simple upgrade requires no engine hardware modifications, and produces 488-550 HP with 537-606 FT-LBS of torque depending on fuel grade. Gains as high as 75-129 HP and 89-168 FT-LBS of torque are available throughout the power band, depending on fuel grade and factory output, making the vehicle exceptionally quicker in all scenarios. 

APR Stage 1 is available for 91, 93, 100, 104, and E60-E85 fuel grades in North America.

Please Note, the 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. 

All APR Software upgrades are only available at our Joplin, Missouri retail location. In order to receive an APR software upgrade, please click here to schedule an appointment. You may either add this item to your cart and purchase online, or may also pay in store.
