We just couldn't get the tune right, my AFR was dipping into the 10's and it was pig fat all weekend. I guess I could have a bad o2. It just wouldn't run after the 660. All my logs before heading there were 11.8 to 12.2 but on the big end we were seeing 10.5 going thru the traps. Can't make power like that for sure.

Assuming your running a return fuel system. Do you think it could be fuel system related? Bad regulator perhaps? Good look figuring it out.
