made some head way on the car this weekend, spoke with dusty at MVP ( awesome guy!) a and we both seem to think its the a mass air flow sensor issue luckly for my bro i have a car just like his :bigthumb: so i will swap mine over to his and give it a try

I'm glad Dusty agrees with me:
Please say 'hi' to him for me, next time you talk. :)

P.S. The current post-turbo MAF configuration could be the very reason that MAF got ruined (if that's the problem)... excess heat or oil from the turbos could easily mess up the sensor. Please keep that in mind before you swap yours into a questionable configuration...

agreed i dont want to screw up my maf sensor..he's order a AEM today so we might not ever know what was wrong with it

ok i need somone to explan! i pulled the car out today hosed off all the dirt hit the engine with some grease lighting and chagned the oil..then took it down the road the car spooled up but didnt die, side note i had the fuel preassure WAY to high, turn it down a bit took it back out and it ran GREAT!! like a monster :dunno: so whats the deal went from being unable to boost to a friggin rocket??

If your fuel pressure was "WAY too high", how was the a:f ratio "around 12.9 before it dies"? Something doesn't add up.

i had adjusted on it before today, when the car was brought in i think it was set at 25 pounds and i had turned it up to 35 so i went up 10 pounds from, but after i readjusted it it stayed right at 13.1 under full boost

well it's not the mass air flow sensor :wtc: back to square one. this car is driving me crazy :nuts: i have no other idea what it could be i've changed or adjusted every sensor that it was pulling codes for.

Did you put the MAF back to the oem configuration (pre-smic/fmic)?

yes sir its back to the oe location

Does it still die at 4000 rpm?
