I almost went with the Upsolute. The problem with that one was that I had to drive to the guy's house and he would do it right there. I just wasn't comfortable with that type of service. Also there was a guy on these boards about a year or so ago that had his done by one of these backyard tuners and they ended up frying his whole ECU. He was able to get it covered under warrantee, but do you really need that hassle?

I've said it before, "you get what you pay for".
