Right now this device is only uploaded with three tunes for a 5.4 (with my specific PCM code)... It can however be reflashed to be used with a 6.0 PSD or most any application, so yes it will work. I looked on 5Star.com and Mike does offer diesel tunes. So if you buy the device from me just send it back to Mike and he'll set it up for you...

If your both still interested let me know...
