CAMARO6 - View Single Post - STFT BANK 1 AND STFT 2 ARE 10% OFF. What could be the cause

mucleman21 · 07-28-2021, 02:59 PM

2018 zl1 with ported blower/snout , TSP cam, 2.3 upper, 5" intake, 103 TB, and 2" header back 3" exhaust, MM Catch Can, Low side pump, running 93.

I'm lost and running out of troubleshooting options. According to my VCM Scanner logs, my STFT 1/2 are 10% apart. seems like I have a vacuum leak of some sort on my bank one.. I've done a leak test by spraying break cleaning along the base of the blower, valve cover, catch can tubes, exhaust manifolds, and pvc lines. I've also cleaned my O2 and wideband sensors, I have 0 leaks coming from my exhaust.
