2003-2005 Cummins Peakside HP Tuners Tune Package

Fits

Everything you need to tune your 2003-2005 5.9L Cummins in one package - the HP Tuners MPVI3 device, the universal credits required to license it, and custom tune files written by Peakside Performance for your truck and your usage.

"Canned" tune files are okay for the average driver, but if you want real performance and adjustability, Peakside builds the file around your specific setup. Tell us what you are doing with the truck and your files are written to match.

We do not support lope tunes or smoke tunes.
