Our HEMI SRT8 Performance ECU Re-calibration provides massive gains in power, torque and throttle response with no other mods, although we can tune for and supply cold air intakes and exhausts etc. We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicles performance and driveability. This is all completed in a day and at the end of this upgrade you will provided with a dyno graph detailing the power & torque increase of your vehicle.
