I have personally experienced cruse control issues if I have cruise on and then change tunes etc. now I turn cruise off, let the truck coast for a millisecond then change tunes and resume. Im betting its whats happening to you. You running a tune, with cruise on then change and the ecm is still running cruise based off the prior ecm setting etc. I feel it should be a warning on the labels/instructions but maybe it doesn't happen enough or we both have strange trucks lol.
