Yeah, I'm just guessing at the problem as of now till I get to pulling the engine out and tearing it down. The engine going in is going to remain stock. Might rebuild this one, might sell it, not sure. I'll keep you posted on what I find. *I hope it was my fault and not the tune. It was just weird how it happened. I was just cruising it around all day, enjoying the weather. Now, the night before, thats a different story. Oh well, I should have gone over engine better before I put it in. Live and learn.
