Message: [QUOTE="TurboM700, post: 1161582, member: 59"] I could not stand the unlock on downshift on mine. (12v in a X with a 4r100) It would actually down shift wait a second unlock the TC then Lock it back up. I changed mine to never unlock on down shift and it seems to be happy. Ok sorry for the derail this isnt about PCS tuning I just know you have a lot of experience in this so I thought I would ask. I actually have one of your PCS files that a very kind memember on here shared. Along with BTS base file. All of which I had to change for my liking. I have found out that tuning a PCS behind a 12v is actually rather diffcult as the TPS doesnt mean ****. The AFC and govnor springs control the throttle. You almost need a rack travel indicator instead of a TPS. [/QUOTE]
