First of all, welcome to the forum! You'll find lots of good info here. If you're looking for more info about these programmers, just do a quick search and you can find tons of pages about this. As for me, I've heard lots of good things about the edge ez, but I've not heard of anyone with the other one you mentioned. BUT, before you do any type of performance upgrade, you gotta ditch your stock lift pump and go with one that can provide enough fuel to your vp to keep it happy! FASS or Airdog are some of the more popular brands. Just do some reading on here and you'll know what I mean. Also get yourself some gauges, at least a fuel pressure gauge so you can keep an eye on how much fuel your injection pump is getting. It won't last long if it doesn't get enough fuel through it.
