Ok so here is what is happening. When I get on it, anything past 10 psi and it starts stumbling pretty bad. I can let off the gas and then get back into it and sometimes it is fine and sometimes it keeps messing up. My current mods list is a little off because I had to strip everything for a warranty repair. So here is my list. Intake, fmic, 255 walbro, 3" downpipe opened before the cat and that is all. I have a aeromotive fpr but have not put it back on yet. I am thinking to much fuel BUT it did not do this before when I didn't have it on and had the 255 in. The warranty work that was done was another motor with less miles on it than the one I have in there now. The old motor never did this. I am looking for direstions to head. Thank you for your help in advance, Keith.
