Yea that just means your cars efficiency isnt 100% a little unburned fuel gets by and into the exhaust and the exhaust is hot enough to ignite it. dont be alarmed.

I think mine does the same thing. I hear this "pop" sound from the rear of the car some time when I shift really fast at high RPM's. I have a test pipe.

Maybe Scott tuned it a bit rich on top end to be on the safe side? What was his insight on this??

Btw, what did you run at the track??

12.5 @108.67 with 85 degree weather and 84% RH It was blazing hot and this was at night. I did pull a low 1.71 60ft and i was trapping 88 in the 8th and ran 12.5@ 103 cause the car pulled 5-6 degrees of timing up top when i tried to powershift 3-4 gear.. Im going back when its cold

cause i tried to powershift 3-4 and the boost spiked to high and the car pulled timing till the boost dropped back to 21-22... That resulted in me running 12.5@ 103
