So I'm gonna put a 5.2 and 42RH in my Valiant and was wondering how tolerant of changes the controller is. I might do a cam swap, it already has a Holley throttle body and headers on it, but I don't know if the computer has been flashed. I still have to crack it open to check for other changes and whatnot.
Any info would help. I thought I saw that the early FAST controllers would plug in also, but I can't find that post now, either.

Thanks
 
It's probably best to tune it. Oem applications don't have much wiggle room, for epa certs.

I'm dumping the purge and egr from it, so I was guessing that was in the works. What tuning options are there for the Mopar PCM?
