Towed my friends 10.1 second Nova to the drags this weekend and decided to run my 2005 2500hd crew cab short bed 2wd. It ran a best of 16.58 @ 82mph with a 2.55 60ft and 10.69 in the 8th. Is this typical 1/4 mile times for a stock crew cab short bed 2wd LLY with 3:73s? First time I ran it I powerbreaked it to 2400rpms and it spun its ass of half way down the track. I was only able to launch it at 1400rpms with no spinning after heating the tires with a lil burnout.

That's what they run.

Cool, can't wait till my Predator gets here. Im just going to run it on the 65hp tune untill I can afford some tranny upgrades. How much will the 65hp tune drop the 1/4 mile times?

If you're running a 16.58 stock, the 65hp tune should put you around 15.5.
