Thanks Boost. Unfortunately, there are way too many variables in your example to help me diagnose my issue. You're running a different fuel pressure and open exhaust. Are you running a SuperCooler or anything for cooling mods? I'm seeing a ridiculously high Air Intake Temp rise during racing. It went as high as 199F with the ambient temp being only 70F. My 1/4mi MPH was also greatly reduced compared to pre-winter mods. I've got a lot to sort out, but it will have to wait til after vacation...
