I have an 07 f250 truck has 40k on it I ran innovatives tunes for about a month and then had problems with the truck "missing" at idle it shakes the entire truck around and the tach will jump about 50-100 rpm. It doesnt matter if it idles normally or if i flip the high idle switch it still idles terrible. I took the truck to the dealership about a month or two ago for the same thing and they kept the truck a week cleaned the turbo and installed new drain lines and changed the egr because they said it was stuck and they reflashed. . . but the truck is still doing it
I';m getting horrible mileage whcih I think may be due to the new flash I can even deal with that I just dont want the truck to run like hole.
