Do i need to? Im thinking why do i need to? Its just gonna retard its way back to near stock setting. I might as well mash on the gas pedal a few more times than usual and have the ecu adjust and adapt from there. What do you guys think? I just installed my exhust 30mins ago. Thanks

 

I just put crawford cats+nismo exhaust on, and I reset it just for the hell of it.. just disconect the batery over night, and pump your brakes like 5 times.
