Alright so ive got an 2004 colorado 3.5l auto (4l60e) with a 62/61 turbo twin tial 38mm MVS. set at 9lbs. 2bar map, 60lb injectors, 450lph in tank. I still have the stock maf. Issue is will i run out of range on my maf, standard 5pin gm maf. I HAVE NOT started any tuning or flash of the pcm yet. currently on my widewand normal driving. I do drive this everyday. it reads pretty well good afr. into the 3psi range the truck freaks out, reduced power mode, main question can i use a maf out of another vehicle that can measure more air flow, or is it worth the effort to drop the maf and go SD?
