From what you are saying it sounds like the IPR or ICP sensor may be bad. Have you checked for any codes with the SCT? Jody is asking for the max in your tuning, so you may be noticing that over what has been done in the tuning of the SCT and stock. Because he is asking for the max, no stacking of chips and ICP mods are necessary with his tunes. The downshifting is a part of Jody's standard tunes. If you don't like it he can remove it.
