absolutley! and lets get this straight..............You have a 60-1 turbo, with a streetport, boosting 15psi on stock tmic??? Oh damn dude I'm supprised your engine lasted this long. Lets say the tmic is working (witch it isn't at 15lbs with a 60-1) your fuel, since it looks like no mods, will be leaning way out with that bigger turbo. You need an upgraded pump with 4x720's for that turbo. Good luck man hopefully it's nothing I mentioned but I fear the worst with the mods you have.

Yeah, samething happened to me, I didnt know it was detonation. I was running 15 psi on To4b with no fuel mods, you need an upgraded fuel pump with at least 720cc all around and a s-afc.
