Not to steal the thread here, but I'm basically doing the same things and one of the comments caught my attention. So far I've added 4.10 gears to match my 35s, a CAI, and catback Flowmaster dual exhaust. Soon I'll be adding Gibson headers and an electric fan (maybe 2..is two worth it or will one be okay?).
Anyways, I noticed someone mention if you go too in depth you'll have to get a new PCM--should I be worried about that already? And if not, when does that become an issue?
