What computer to use for EFI in my Dart

I've tried that before back when I had a Dakota. The factory computers don't have the ability to compensate for the strokers and bigger cams.

You didn't use an SCT Tuner with a custom tune then. I used a '98 PCM for a manual trans and a Hotwire Auto Hot Rod harness on my 5.9 & later on my 500+ hp 408 with a pretty large cam on a 108* LSA. I just drove it from the Bay Area to LA for Fall Fling yesterday and got 17 mpg averaging 70mph.
