[Crimson600+HP]

I don't have a picture of the piston itself right now. It was as you described though, like waves all coming from the base of the piston near one of the rings. Most likely the cylinder was hot enough where the ring closed the gap and there goes the piston. Once I get my hands on the piston, I'll be sure to check it out.

Last thing I have to do actually is a crank position relearn that has to be done at the Ford Dealer. Started throwing random misfires above 3K RPM. Something I didn't know had to happen and my mechanic forgot about. No big deal, appointment scheduled tomorrow morning because a Ford Dealer's IDS tool is the only thing that can do this. Too bad I have to return it to stock tune before they can do this procedure. Looks like my car will run shitty from the parking lot until they do this relearn procedure. Then I can return my custom tunes back on once they are done.

Getting closer every day to having my car fully back.
