Truck shaking after test drive!

Your oil was hot and thin. Your cam phasers didn't lock in place and the cam timing was off. Why it seems to happen backing up, I have no idea, but exactly the same thing has happened to me in the past as well as other people. It's a 5.4l 3v issue.
Had nothing to do with the tune.
