Message: [QUOTE="chappy, post: 350270, member: 196"] My pmax is doing that crap when I go to accelerate hard and downshift. For instance passing someone. Only does it on a couple of the bigger tunes. I tore mine out and no sticking vains but a pretty worn unison ring. The turbo probably has 15k at the most on it and it was worn baddly where the actuator rides in it. Almost looked like it wasnt set in correctly from the factory and worn just one side really bad. I can say though that you need to check the wiring for chaffed spots. I found a chaffed wire where it had melted on the turbo oil supply tube and it was a map sensor wire. Was sending wrong signals I assume and don't know but ended up having my accelerator pedal fail shortly after. It still likes to stick on the hot tune but way better now that the other stuff is fixed. I assume mine is sticking due to the unison ring wearing funny on mine but yours could be a wire issue somewhere. I spent weeks trying to research and come up with what it could be. [/QUOTE]
