With a million miles on it it's time for an inframe, new balancer and possibly new cams as well.

That's all you need to know about it right now lol.

What do you mean exactly by demandate? I have 3 other trucks 2007 t600 with c15. I’ve had isx before in my 02 03 international back in the day. I’ve ran the overhead and serviced it and drive it today. It ran awesome and is getting around 6.7 ton7 mpg. According to my scan gauge I use in my trucks. This truck has 3.55 in it with a 10 speed. The turbo is only 20k miles on it. Not sure about an oh or exactly how many miles are in it. Im guess right at 1 million. The dash shows it but the computer shows 115k. lol so who knows. I was told it’s deleted and it is. Everything is gone except for the egr. I change my oil every 10 k. I’m a local grain hauler within a 150 mile radius usually. I told my guy I need a copy of the files on my ecm to send to rawze!!?? If so I will be working on it. Id love to know if the tune that’s in it now is safe. I’m all about fuel mileage and enough power to get the job done and keep my motor safe. Whatever kind of tune or oem setting that is. Thank you for the help. I know my accerts but want to stay up on the cm871. Thank you
