I guess I'm going to have to fix that terrible problem.

Art, if your na and it's doing that, your over fueling it. If so, try leaning it at the launch RPM and you'r likely to be faster. You evidently talked to the wrong person at FAST, as I have gotten people help with the older systems too. There are some very bright, helpful people there. I'm sorry you had problems, but if your pushing fuel past the rings on the 2 step, you still have something wrong.
That is a lot fo fuel. I wonder if the Lingenfelter 2 step is screwing with your ECU? If your battery is not grounded to the engine you might run a ground cable all the way to the engine. The biggest source of problems with EFI is grounds.
Heck, you may be as far under as the Caddy in Stock when you get it fixed.
4500 isn't very high, how big is your engine?
