hmm...i never reset my ECU after i did my exhaust...which was probably 700 miles ago. do you think it has relearned by now? or should i just go out and do a reset now. i didnt want to lose my stereo settings, so i just left it alone. is there power or tuning to be had if i do reset? thanks in advance.
Depends if the ECU had already completed the learn function prior to your exhaust install. How many miles on the car when you completed the exhaust upgrade?
If its a cat-back, I would just leave it alone.
If its a TBE and your car already learned prior to install, then I think you will be more than happy re-programming those radio stations!
