lol very funny guys. but seriously it sorta feels like a muffler vibration. but it sounds like the truck revs up a little.
Not trying to be funny at all. Just trying to help get to the bottom of the issue. If it is exhaust related, then I would begin by checking all of the clamps and exhaust hangers for security.
If it is throttle related, do you have or have you recently installed a custom tune? Throttle response is affected sometimes with tunes.
A little more info is needed to help you diagnose your problem as we have never heard of 'blimping'......
