Question Maf Help!!!****

MAF screen in or out on my 2003 2500 HD 6.0?
Cold air kit, exhaust, and VR TB stack.
What to do? I know the ls1 gains 4-7 rwhp with the screen out. back in the day i made 5 rwhp on the dyno just by poping the screen.
Thanks

Yeah, but the computer will set things back to normal settings, and you loose the performance gain after a couple of days of driving. If you get a computer tune, then can tune it to give you a tune that will take into account the descreened MAFs and not loose the performance on it.

leave it in, or you'll go lean as all hell.... unless you have the PCM reprogrammed for it.
