They called me today and said it only had 10 psi of fuel pressure. They also said they checked it when they had it running and it was 58 or 60 where it should be. Would the low fuel pressure cause it to run rich? I also told them to look at the vaccum lines. I wanna get down there and check it out myself.

Now the dealer just called me back and said it started right up and is running great with plenty of fuel pressure and the idle is 14.7-14.8 not running rough or like **** either. I'm at a loss to what the hells going on. They checked all the vaccum hoses and they said its running with plenty of vaccum.

what is your fuel setup besides 60lbhr injectors? if its stock then the regulator is in the tank. shouldn't make it run rich with low psi but it would make it die for sure. maybe i mised something but if they added fuel at idle but no where else then that why it was rich at idle and not while driving. it more than likely didn't need the added fuel but it looked like it due to low fuel pressure. i would say take the added amount of fuel back out and fix the fuel pressure issue and it will be good. if your running stock pump at 10psi it may have just worn it out having to run full out while in boost. i know mine use to drop pressure during a good run. it would not g
