I might need to lift to get it out in second. Not sure what the truck with me weighs, but im about 225, i had a full tank, had the gate and spare on. Next time I'll try not to eat for a day.

Going from a full tank to about a 1/4 is 100#'s so that's another tenth and mph, then the spare and gate are another tenth and mph. I guess those gains would be the same up there in that air. If you came down to a track like Houston Raceway Park during one of these winter months and pulled that weight, got good traction out of the hole, throw some race gas and up the boost a couple #'s, I could see an 11 out of that truck.

Don't worry, I'll catch ya! lol

HAHA, It's just a small cam, almost the same as a Z06 cam. Most of the guys on here would tell me not to waste my time installing it

you still got 32ci on me

. I must just be a better tuner

Your truck should weigh about the same as mine. Full of gas with spare, its right around 5300# w/out me.

Thanks again everyone. Ive got a mail order tune. I need to get a street or dyno tune done. I know nothing about tuning. Hey kyle are you running a stock TC? I wonder how that effects things with the turbo.

I actually have a stall. I forgot to mention my 3rd run that didn't count. At the light staging, had my foot barried in the brake building up boost. well I made too much boost for the brakes to hold, front end on the truck lifted up roasted the front tires and blew through the brakes before the light even went green ha ha! That **** pissed me off it would have been one hell of a run. lol
