RE: 2005 Volvo Cummins15 CM870 TURBO SURGING UP AND DOWN
I just bought a truck with cm870 and I am kinda having the same problem except my turbo won’t build but about 10 psi then kick out for a second then boost back to 10psi. I am positive it’s a bad tune. So my question is do you have to have insite to be able to pull the file so I can have it looked at?

Forum member 'running rough' is the person who does most of the CM870's for people on here these days due to them being so quirky to flash correctly vs any other model ISX.
