u sure it has less than 400k miles on it?.. if not then u need to replace its guts.

Yes has around 60,000 miles on new parts. They was nothing wrong with it when I had it taken apart and parts replaced. I did get registered with cummins insite and the motor is a isx15 450st.

Just want to chime in, for the OP or anyone else reading. When talking about "load" we're referring to engine load, not cargo load. How hard the engine has to work. Yes, there is some correlation between the 2, but they are not the same thing. Just wanted to clarify that, as it's mentioned frequently here but with the assumption that everyone understands the terminology.

I’ve tried to call the guy in griffin ga 3 different times he was supposed to call me back and didn’t is this the normal for him? Every time a lady answers the phone says he will call me back.

Me Hagg a busy guy, one of the very few shops that can successfully diagnose and repair an ISX motor along with being able to correctly tune one. Sad state of affairs, and true.
