BD sells an R.A.D.-Racers Anti Defueler, which is what I assume you are looking for because the truck will defuel itself stock. They run about 250-300 dollars. I have one and I don't like it a whole lot, it throws up trouble codes everytime you use it, and messes with the gauges in the dash. I would just get something like an Edge drag comp, they fuel all the way up to 3300 rpm. If you don't have a fueling box already, that is probably the best place to start, they cost a bit more, but you'll be happy.
