Best of luck and hope you get it fixed fast. For those mods you shouldn't have had any issues. Definitely was the tune. I was really confused about your tuner telling you the 93 tune and Race Gas tune where the same??? That sounds like a big blunder to me. Those are two different worlds. I mean you can't run the amount of timing you would on Race Gas when running 93 octane. Was it some sort of flex tune?
But in the end if the tune was set for race gas (more timing etc etc) and you were running a mix of lets say 98 octane average then I'm betting that's what caused the damage.
