ARP head studs, Personal SCT tuning, MBRP exhaust, AIRRAID intake, Bully Technocolor Intercooler. It's not hard to get those diesels to run good times especially launching in 4x4.

A lot of $ invested? Nope. Just under $1,500. The d'max with their weak front axles and a generic edge tune are running the 1/4 in the mid to high 12s. That was on Speed channel a few months ago. Put exhaust and an intake on them and they move pretty well, but then parts start needing replaced.

When the truck launches at 2,000 Rpms and it is putting down over 600 FT/TQ. The bad part is finding dyno shops that will let you bring a diesel in to get it tuned properly. Most dont have the ventilation system to handle the smoke.
