85mm MAF
Is the Z06 85mm MAF a direct swap out on a 98 C5? Is there a measurable power gain to be had with this upgrade on a heads/cam bolt-on car with ported throttle body?
Is re-program required? thanks.

A) Five wire harness adaptor required due to integral IAT sensor in 85 mm MAF
B) Being that the 85 mm MAF is a larger diameter, the airbridge and hose couplings need to be changed/modified
C) PCM calibration will not be correct so you will need to alter at the PCM level or you can try a resistor to "trick" the PCM..or both
D) after all is said and done, there won't be a meaningful power gain to support the effort

GM HighTech Magazine just did an article with the 85 mm MAF swap and it made only 2.8 HP. I really think thee are much easier ways to gain that small amount of power without the possibility of getting error codes.
