TR220 cam
Fi-Tech 102mm Intake
Long tube headers
Without the MAF, starts and goes straight to idle, throttle is responsive, revs with no issue.
Connect MAF, it starts won't will only idle a few seconds, won't take throttle.
I am using a stock 5.3l tune with the cylinder volume for the 5.7l
I'm at a loss as to where to start tuning with the MAF
Help would be greatly appreciated!
