Anyone please weigh in. 2015 GT Convertible. At the time, Cat back with x pipe only mod.
A while back I missed a shift and over revved my GT while tearing it up on the back roads. O/R'd it bad enough to shred the clutch disk. Limped the car a few miles home, and knew that it was clutch related, but there was something else... Engine felt weird too. But I couldn't put my finger on it.
After I installed my McLeod RXT twin disc, I fired up the car and went for a drive. The car felt sloppy and sluggish. But I was trying not to hurt the new clutch. After a handful of drive cycles, it began to violently miss at 2100-2300 rpm. Then threw a cel and indicated misfires cyl 5 and 7 (if I'm remembering)
I wasn't sure whether I missed a step doing the clutch, or ruined something but drove it a few more times with the same results each time. Finally booked it in for warranty (it's 2 hours to the dealer, no courtesy cars). They claim that the did a COP test, a compression test, and new plugs on the affected cylinders, and then a cylinder relearn. I had one of the mechanics (I know him through a mutual friend) drive it a couple days to and from his home to make sure I didn't go get it only to have it act up again on the way home.
Here's the thing, although the CEL doesn't light up, and the violent bucking is gone I don't think they actually fixed it. It feels different. It's still has a stutter at low rpms that I don't remember, but it's like the ECM sees what is happening and is just about to throw the CEL but then goes "Oh yeah, I remember I'm supposed to ignore this" and then it goes away. Still doesn't feel as crisp as before.
Any thoughts? I'm not sure how to even test something like "it feels different"? I Want to add twin boosting devices to it so warranty will not be looking into anything after that. Need to know I'm adding hairdryers to a sound engine.
