The one thing i'm worried about is you are using a FMU that runs on boost.... if i was in your situation i would use a piggyback or even a standalone to tune it.. are you using anything to pull out timing? (this wont matter much until you get to 7psi) but i've heard lots of horror stories about FMU's...
But damn... i love the work you've put into your truck... i think this is the 5th time i've said it <img src="/forums/images/graemlins/lol.gif" alt="" />
