    Hptuners or EFIlive are the best tools out there to tune with.

    Check your tps first and make sure it is were it is supossed to be and that it is not going bad. On lt1's thats the main problem. I think LS1's have one as well. If it is under voltage it wont down shift cause the pcm isn't seeing WOT or Planted as you called it.
