I think you will like the DP, the tunes on it are awsome, works with the trans sifts and I belive it adjusts the fuel as well, thats why they don't recomend stacking it. You can call Jody direct or I got mine from ITP. Dennis over at ITP was a great help when I was deciding wich way to go, Check out his site. He has a small forum for discusing his parts, and any Questions you may have about them.
