I don’t (currently) want a “tuner” type module. My performance is fine with my setup and my dealer doesn’t like them. I’ve read that you can reset you Jeep back to stock after using a programmer, and read that you can’t, but for me it doesn’t matter because the power I have with my setup is fine.
So for me the ProCal is perfect - I have my tire size, tire pressure, and gears setup perfectly (as far as the computers are concerned).
