Hi All,

My last two track days have ended with a P0102 (Low MAF Voltage) code and the car in limp. I unplugged the battery for 30min + put in a brand new MAF sensor + housing, but same issue.

Previous owner installed an '06 intake with velocity stack and a 350evo Bored Throttle Body. The car has been dyno - tuned professionally through UpRev (not tuned by UpRev themselves)

Anyone here run into MAF issue when they went aftermarket with their throttle body?
If I go back to a stock throttle body, will I need a re-tune or can I do a throttle body relearn?

*The car runs fine around the street or at 70% on the track. Only after a few laps of pushing the car will this code get thrown*

Found the issue. It was a shortage in my MAF wiring from the MAF plug to ECU. The shortage was where the wiring goes through the firewall to the ECU.
