Message: [QUOTE="Back woods, post: 1507446, member: 28164"] Gave the tuner to a friend of mine and it will only work on another vehicle if mine is put back to stock. Truck has an ATS housing, 6637 and 4" turbo back. Doesn't hold high rpms between the 1-2 shift unless I floor it. Driving slow it will have a slight delay and if you peddle it just right it can really slam. One thing I have read is a bad accumulator spring will shift good when it is cold and get rough when it warms up. It will do the same when cold and then get rough but if I roll into the throttle smooth out. [/QUOTE]
