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?
