I have the Tri- ax and it's alright, but after hearing so much positive feedback about the MGW, I had to get one. I ordered it yesterday can't wait to try it. I'm one of those people who will doesn't mind buying things twice, because if I can hit 3rd a ten thousandth of a second faster, well that's faster. Which also means that I have a ton of slightly used parts that I've accumulated over the years. Also anybody with a '03-'04 6.0 Powerstrke that wants a chip or programmer I have several different makes. I also have a turbo and and set of ladder bars and a fass fuel system for a LLY Duramax.
