I'm going to get my Bus dyno'd this spring. I have only the bolt-on RS-3's. Can the ECU be re-mapped or do I need a PC for this? Is there a benefit to one way or another, or should I just leave it be? I'm thinking if the PC craps, I just unplug it and go, if the ECU goes....
I have no problems with backfiring and it seems to run just fine. It ain't broke, should I futz with it?
Input?
