SATX_CammedMaro

I have a 2016 camaro ss . ive bought it about 2 years ago and it's been great ( I did buy it already built for me ) . But as of about 2 weeks ago it started to die on me or if it stays on it was getting choked up. well I took it to a mechanic who can work on these type of performance cars and he couldn't find the problem . but on my way home I noticed it shakes different then it did before . the roar or rumble it had also sounds different now. ive also notice as I drive the exhaust sound different and revs high . any one have any idea what could be going on ? ive tried a tune shop to see if my maybe something was off on my tune but he sent me to another shop but my appointment isn't for a couple of weeks, and its my daily that I miss driving . just to not it does have a cam a tune and runes on e85.

Tunes don't change....so if it ran good before, the issue is likely mechanical. Need to log data...check for misfires, log fuel trims, and fuel pressures.
