I have a Bullydog powerpup programmer for sale that fits the 03-04.5 dodge cummins diesel. Reason for selling is that now I have an 05 and the chip will not work for it. Asking $400. Less than a yeard old. 4 settings, stock, tow, performance and extreme. Supposedly 50 horse for the tow, 90 for the performance and 140 for the extreme. Really made a difference to my 03 and when I drove normal gained 3-4 mpg hand checked.

 

Offer has been dropped to $350 and I will pay the shipping so long as you are in the lower 48.
