i just started my car and have nothing but problems. it won't idle it just dies, i have to keep the revs around 1,000 to keep running. if i punch it, it is fine no problem, but there is also no boost either. i don't know what to do please help.

Disconnect the turbo oil inlet to see if oil will squirt out from it (have a bottle or something to catch the oil.) That will show if there's oil pressure. Doublecheck to make sure all your vacuum hoses are hooked up. The car won't stay idle if there's a big vacuum leak. Do you have a fuel pressure gauge hooked up? Any fuel pressure? I also noticed you have an S-AFC. Check the wiring again.

Let's worry about the no boost problem later and work on the idle first. Did you change out the injectors? If so what size do you have now? Also another thing to check would be the amount of FP you have at idle.
If you just installed your AFC I would try just leaning it out a couple % at idle till it idles. It sounds like you are running to rich to idle. Give it a try and let us know what happens.

yeah my setup is, 370 cc injectors, safc, fmu. i have a fuel pressure gauge, but no line for it. is there anyone in the area that could come and help? i don't even know where to begin.

well, i'm looking at it like this. i don't have the sfmu, i have no way to adjust the idle pressure. the only thing that i can think of right now is, when i hooked up the safc all dualgen2 settings were still in there. i think i am going to reset the safc when i get over to the car later. any other ideas? i need the car for tuesday.

With 370cc injects, running stock fuel pressure(around 48 psi), you have way to much fuel at idle. Surprised it even runs You are going to have to lean out on the SAFC quite a bit, start at -10%, and work on up from there until it idles good. Just remember, when you take out more than 10% with the SAFC, it may increase your ignition timing to the point of detonation, and that is NOT good. I highly recomend a SFMU to lower your idle fuel pressures, and basically just use that mainly for fuel tuning, and then just use no more than 10% with the SAFC to fine tune with. And yes, you NEED a fuel pressure gauge. Don't even try to tune it without one!!!
