Hey guys - I have the truck that shift HARD and falls on it's face at 1 to 2 and 2 to 3. Although it runs fine - I really need to tame the shift down just a touch and ask why it falls flat right after the shift. Every now an then the traction control light flashes while it falls flat. I am attaching the current and original tunes. (This is follow up from my previous post which must have fell through the crack). BTW - it only does this under WOT.
Thanks for anything you can do.
