    still waiting for allen or john to call me back, but i put my scanner on the truck today and everything seems pretty normal... except my fuel trims are very rich. at idle my long term trims are -20ish and when i start driving long and short term fuel trims go -30 to -60 that seems very! rich is it possible that too rich would be causing my problems stalling when i come to a stop, and sputtering when i get on it?

    Sounds like you've got a bad fuel pressure regulater and you're getting too much fuel pressure flooding the engine.

    hmm ill pop the gauge on it when i get a chance last time a checked i had a solid 64-65 psi but ill look again.. could'nt it just be in the tune too? when boost hits the fuel trims level out to 0 but when no boost they are way rich

    52-62 is the acceptable range last I checked. LS1's run at a fixed 58 PSI.
