Truck jump forward

I just got my new injectors and chip back in the truck. It runs great but if I'm going down the road and build a little boost, 20 pounds or so, and then let completely off the pedal to coast for a couple second, as soon as I touch the throttle the truck jerks/surges forward one time. If i build boost and then just let off but not quite all of the way I can simply mash it again with no jerk, so it's only happening when it builds a lil boost and I let completely off. It's a pretty solid jerk when it does it and that's with no load behind the truck. I would think it's probably gonna be a lot worse when I get around to pulling stuff agian and having to build boost on every hill. Any clues?

Re: Truck jump forward

mine had lots of play in the rear end. let off all way, goes tight one way, they when you mash it, slams other way, if you dont let off, it dont go from one side to other, thus no jerk. was my issue.
