no i watched the sample video you uploaded it was identical to what i had going on. it would go away if i pryed the arm up. truck also built way too much boost while cruising, do you have quickserve? they have the spec for how much air pressure should be applied to vgt in warmup mode. i wouldnt advise disabling the vgt. i tried that while i was testing, jakes were shi#t and had poor low end power.
