Bully Dog has merged their excellent diesel tuning knowledge into this small and easy to use downloader for the 7.3L Powerstroke. The downloader plugs in through the OBDII port and gives you the option to download 50hp, 75hp or 120hp programs (on 1999-1/2 to 2003 models). During dyno testing on a 2000 Ford 7.3L Powerstroke the downloader added 60hp and 131 ft.-lbs on the 50hp setting, 78hp and 150 ft.-lbs on the 75hp setting and 119hp and 202 ft-lbs on the 120hp setting. The Power Pup 7.3L will also remove the speed-limiter (1999-newer only) and can erase engine Diagnostic Trouble Codes (DTC) on all models.
