Hello everyone
So Iv having some pretty bad issues with my 17 a8 camaro ss
I recently got a transmission tune and after couple of hours I started Hearing a strange noise like humming sound and couple of minutes later my car stalled out , I then drove home. Next day I tried leaving home but it stalled out again, this time it jerked on me pretty bad. It happens either when I give it gas or when I’m coming to a stop. There’s no check engine light aswell for it . Has anyone came across this. Just a bolt on car flex fuel, ported intake manifold/ throttle body , speed engineering headers and tcm tune.

Sounds like a bad tune if the problems started a few hour after you got the tune. Flex fuel requires an ECM tune to enable it so your car probably has both ECM and TCM tuned. Contact your tuner to have them check it out.

Yes that’s actually the first thing I did , obviously tuner denied it had anything to do with it but I actually took it to a local shop and switched to a local good tuner looked over tune he did find some things the other guy shouldn’t of touched we tested car it was working fine drove home and stalled again at a light after 30min drive. Next thing I’m going to do is take off front bumper and see where I took off tcm to see if maybe I accidentally pinched a cable or disconnect something that wasn’t while I took it off
