I have seen Matt from Spartan Diesel on the track (not in person, a video), and that truck was fast as h*ll. I know the 08 d-max is fast too, I use to drive one for work. It's always a weight thing from what I've seen, so if his body configuration is the same and weight isn't too big of a diff, I think it would be a close race. Let us know how it turns out.
PS Matts truck is far from stock
