So I have a 2022 matryx 850 boost. Just hit 2,000 miles on it. Everything is stock and doesn't have the updated mapping. I've always run 91 non-eth in it. On the way out last ride I noticed a small bog on the bottom end. Probably had around 15 miles back to the truck. As I rode back the bog got progressively worse. It was still able to pull through the bog and come up on boost and run fine on the top end. If I had it up in rpm occasionally I would get the "maximum detonation detected" warning and it would go into limp mode. Went to trouble shoot it a couple days later and it wouldn't come through the bog and just seemed to be in that limp mode the whole time without the warning. Switched spark plugs, drained gas and replaced with av gas and still the same problem. Did a compression test and mag side showed 100 psi and pto showed 110. Took the pipe off and put a bore scope in the y-pipe and saw my mag side piston is scuffed. I plan on doing a top end rebuild but don't want to hurt it again if there is a bigger problem such as reeds/injectors/wiring harness I'm not aware of. Any suggestions on moving forward before I start the teardown?
