its been a long time since i ran track but your times seem real good to me.
2005 Chevrolet Silverado LT Duramax/Allison 4x4
FPE Tuned (dsp5)
FPE Tranny (suncoast 3)
FPE Turbo (68mm)
FPE Tapshifter (sweet)
Airdog 150 (very quiet)
The turbo sounds sweet with muffler,bet it is way loud without muffler.
Thanks to Fleece Performance,the truck has been flawless. Nobody wants to play anymore
