I've changed the exhaust and been doing some tuning on my own with it via Efi Live. Stock motor, stock turbo, no nitrous or propane, just #2 diesel.
12.75 @ 108.449 mph right off the street.
Not bad for 7000 pounds. I need to lower the torsion bars and air in the tires to get it to leave harder. At the track it wheel hopped badly, whereas on the street it just launches. The sticky track is much harder to navigate. I left the front end up and 70 psi in the tires, so this is truly how the truck runs everyday. Still had 1.84 60's which isn't bad, but I know there's more. The mph shows it could run a low 12.
At any rate, I'm more than happy as this truck get 15-16 mpg around town and 19-20 at 75 mph on the freeway, and scoots pretty good I'd say.
