    sounds like the converter is hanging locked up at deceleration/coming to a stop. The first issue sounds like the 3/4 pack is about to buy the farm.

    Well a little update, today I recieved a new tune "without even knowing". and just as I figured it is worst then the last. If I would have been called back to tell him the problem maybe it would have been better!!!

    Could all his problems somehow be linked to a impending tranny failure? According to his sig he only has a verter, shift kit, servo and has alot of power going to it.... Maybe all the parts not upraded are about to go pop?

    this is a prime example of why i dont run mail order tunes anymore. get someone local that knows what their doing and fix the tune and also check to see if the trans is hurt or not.
