umm nope ran a 12.33 full weight minus spare after that run in sig, remember I was still learning how to tune back then, if I could do it all over again now it would be in the 11's.

oh by the way this is with stock truck intake, and stock water pump.

they say 10-15 hp with elect. water pump and 10-15 hp with ls6,fast intakes but I disagree as I did the swap and lost HP. good luck to the op.
