Hello I am new to the forum! I am having an issue with one of my GTX wakes. It will only go up to 6400 RPM's WOT. Here is what I have tried. Changed spark plugs, fuel pump and filters, swapped coil packs with the other one that runs fine, ran it with the seats off, checked throttle travel, checked oil lvl, checked compression on cylinders - 162, 165, 178. When I take it out it runs at 5800rpms then after a few minutes will increase rpm to 6400. It also misfires at 3500rpms sounds like popping out of the exhaust. Is that compression ok? any other ideas?
