I know this is prolly a stupid question but is anyone on here doing any hd Cummins tuning? I am looking for some info on a Cummins truck and was wondering if anyone in here has been playing with the hd stuff
I should have said that I’m not looking for tunes. I have a truck and am having some issues with it and I am looking for some starting points at where it should be around idling and I can diagnose from there.
