The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle's hardware. With the ECU Upgrade alone, APR's Calibration Experts measured higher peak figures of 334 ft-lbs of torque and 247 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 129 ft-lbs of torque and 90 horsepower. The increase in power directly translates to an exceptionally quicker vehicle. Using advanced GPS measuring devices, APR's engineers conducted several acceleration tests. During the 60-120 mph sprint, the APR Stage I equipped vehicle finished 11.6 seconds faster!
