I gues I just got the full PRP moved from another car to my Mach1. I was wondering if anyone has any input on things that I should change that are simple basics or things to NEVER touch. I dont have enought mods to ned a dyno tune so right now I'd just like to tweak the timing some. But I'm not sure what settings are safe on the Mod v4 4.6
EDIT: Also what is a 2 step rev limiter? My last car didn't support this.
