[QUOTE="war21789, post: 10441996, member: 112302"] ok, got a 95 5.0. stock long block including cam, Trick Flow r- series(not the box) intake, Boost Brothers turbo kit running 6 psi, 90mm lightning maf, 42# injectors on stock fuel rail, adjustable regulator, walbro forced induction 255lph fuel pump, msd coil, slp lm1 catback. might of forgot something but thats tha majority of it. the problem, runs good up to 3500 rpm after that it goes lean, starts missing, poping and not running worth a crap. Fuel pressure set at 40 psi. we just swapped the fuel pump hoping it would fix the problem but it didnt. none of the fuel lines are crimped or in a bind. thought it might be the fuel rails but theres people pushing 500 hp on them. also heard a few things about needing a boost specific fuel pressure regulator but dont have one of them yet. were only runnin 6 lbs of boost. it does have an SCT chip with a partial tune on it we found all of this out on the dyno. maf is not pegging. just wondering if anybody happens to know anything about what the problem could be or if anybody else has had this problem.
