This is not the regular cylinder #8 issue. This is a different problem. The scope revealed a black piston head, which means it was running rich. If it were blued or discolored that would be a sign of running lean, combine with heat would be a tune issue in my experience. It's definitely a head scratcher right now until we dive into the block.

I would say be aware that you are going to lose your warranty, unless you get an FRPP kit and have ford install it. But you will pay a ton of money, probably what I will pay to buy the kit, put it on, then forge the internals. If you want to boost, do it.

Best course of action, trade in and get a 13+ GT500 lol
