Got a check engine light for a misfire on #5 piston. Took it to a shop and found out that the piston cracked. Dealer won't cover it due to the mods in the sig and the Bama tune. Kinda bummed. And kinda out a few grand. And kinda have an angry wife. Shop thinks it might be the tune that caused it. Having the engine built with forged internals for boost in the future and getting it dyno tuned. Sort of a silver lining. Ok end sad post.
