Any one know of a tuner that lets you make your own programs, or edit the ones that come with it. Ther are tuners like that for gassers and I have heard of one for the d-max, but it would be coold to adjust the tune on a laptop , and make your own programs.

 

None to my knowledge. I've got a dynojet box on my bike to adjust fuel maps via a laptop and would love to see something like that in the future for the cummins.

 

Thats exactly what I was thinking about, something where you could adjust timeing and fuel with a laptop. That would be awesome.
