hey guys hows it goin? i been browsing around this site for some time now . i have a 2000 pontiac sunfire with the 2200 and a 4 speed auto. right now it has the j tuners turbo and intercooler kit on it . my fuel mods are 310 cc injectors and a catech fmu . its been running like crap for a while now and i talked to a shop thats around where i live and they said its because i have to big of injectors on . when i first start it up a lot of black smoke and it sputters a lot . and it will stal itself out sometimes. i figured since the guys on j tuners did it that it would work but i guess not . i don't know . is this true?they told me that i would run great if i put back my stock injectors and just kept the fmu on . i'm running 5 psi . thanks for the help .
