Re: Maf

Datalog or swap it out to verify

You can also try cleaning it with Maf specific cleaner

Re: Maf

According to my tuner the signal from the Maf is good. I put my car on the dyno the car made 384 rwhp on the first pass and on the second pass we turn the maf about half inch in and the car made 599 rwhp and the power came from 5000 rpm to 7000.

Turning the MAF doesn't add power. Power comes from adding timing, boost, and adjusting the A/F. Turning the MAF just cleans up the signal.

Yes you are right but gaining 200 hp just by turning the maf is not right.
