good morning guys,
I have this 6.0 with ls3 heads and truck intake 90mm throttle body problem is I cannot get the maf sensor to fail correctly, the harness im using is from a 2003 Silverado with the maf/iat sensor together, so everytime I tried to fail the maf its makes the whole tune surge and car sputters when trying to give it gas
