Certainly possible. Sounds like the correction is pretty sparse though. Do you feel like your exhaust is particularly crackly when it happens? Whenever I crackle real loud my corrections are hella high, but only in that moment. On my crackle tune, it pops quite loud right at 3500rpm, and that’s always where the correction is. Might just be the knock sensor picking it up, thinking it’s knock.
Or I could be way wrong, just a deductive guess.
My exhaust gurgles all the time, especially when cold, however I've never noticed negative corrections when it does go " bang " out the back end. I'm starting to think I'm all good for the most part. I dont feel like the car bogs down or anything like that, if anything it pulls harder in the higher gears then ever and actually pops when I shift from 3rd to 4th if I hammer it. But no, never any corrections when she goes pop or bang, its just at the most random of times.
I'm gonns run it till I get my FMIC and stratified tune installed ( about a week hopefully ) and see what the difference is. Its highly possible COBB programs it to aggressively reduce timing as stratified mentions they do at the first sign of knock.
I'm also thinking it may be false knock, ive read if something is loose on the car the knocm sensors may register false knock..... I'll be 100% honest, I was a monster with that manifold heat shield when I did the down pipe and im sure the mechanics had a hell of a time putting it back on ( i bent the sh** out of it in rage) and it does rattle at about 2k rpm briefly, im wondering if it also rattles at higher rpms but I just can't hear it cause my car is obnoxiously loud.
This is why I love cars, did I break it? Or is it just doing its thang who knows? She's also old, thats a factor as well. God love her though.
