Bully Dog.
Saw a Bully Dog equipped Duramax turn an 11.49 quarter at 117 MPH, with a 1.70 60 foot time. Not bad for a 6500# pickup truck. If you want to do diesel in a pickup, Bully Dog is the way to go.
CORRECTION
The tag line for this says nolimitdiesel, but I heard this truck is Bully Dog equipped. Could be wrong.
http://www.nolimitdieselperformance.com/eleven.mpgI have customers in Norway, they LOVE the Duramax, and thier first two "accessories" are a Bully Dog programmer, and a K&N air filter. Followed quickly by a Flowmaster muffler, or trashing the stock muffler and going without, although some use the Bully Dog exhaust, often with a Flowmaster muffler. Many report about 20-21 MPG with a Duramax in a crewcab dooley, and the ability to pick on lots of "sporty" cars. Same stuff is popular here as well.
I'll keep my RAT powered trucks though, my big block Chevy crewcab dooley looks like a refugee from the recycler's lot. Makes it all the more embarassing for those kids unfortunate enough to choose it off.
