I have had my ported tb for a while now and the two things I noticed are that it made the truck respond better off the line and my 0-60 times dropped. I don't recall off hand how much they dropped but the drop did correspond to the better response I was feeling off the line.

For ordering one, what I did was just have Dan buy a new TB, port it out and then when I got it I sold the stocker to recoup part of the cost. It just made it easier for me bc I couldn't afford to have my truck down for a few days.
