Another "Is Fuel Injection a Worthwhile Upgrade?" Question

I have the Fitech Dual Power Adders on my Duster with a 6-71 blower, some of the best money I have spent on it. Runs amazing and easy to tune. People critique Fitech, but I think most of the problems people seem to have are user related. I followed the instructions to the letter, and got some great help from other people on this website when in doubt and it fired up and ran great right away once I was finished installing it.
