Diesel Reprogrammers, gotta love em

Put a Bully Dog reprogrammer in the Dodge and man does she scoot.
Being the cheap

that I am, I did the "try before you buy" promo. What sucks is that it only lasts for 3 days, then reverts back to stock.
Going to add and airbox, change the muffler then add a reprogrammer eventually. Don't want to run into a snag with the warranty.
