MAF+TPI+BOOST=???

i have a trans am that came stock with a 305 tpi+maf, i put a 350 with LT1 injectors (24#) walbro 255lph and bought a "custom" prom for my setup from TPIChips, car runs fine BUT its time to make it faster so im going with a single turbo, i'm not trying to go all out just 5-6 psi on a t70 to make it a bit faster. my question is can i get away with using an adjustable FMU for now and not have any problems or check engine light due to the MAF?? i will be putting the MAF before the turbo.

Thanks in advance!

There is no way 24# injectors will be enough. You need at least 42's to be safe. Once you hit boost, tuning/fuel usage is a totally different animal. I think you should get a stand alone system like DFI or Big Stuff before you blow your engine trying to get a chip burned.

Plus a 70 trim turbo is pretty large. At 5 lbs of boost, I would bet you could see 550 hp to the wheels- if you had the right tuning/fuel
