HaHa!! After six months I've finally had some success. I've got the car running pretty good now. For those of you that don't know the story, I bolted on a set of ported L98 heads, Torker II intake, 670 TBI, and 1.6 roller rockers. Once it was bolted back together it wasn't running right. Turns out that it needed a some custom PROM tuning...to make a long (six month) story short I chased my tail with ECU swaps and PROM burning 'till I ordered one from Fast Chip. It's running really strong now except that its got a stumble right around 1500-2000 RPM's when you womp on it. Anybody got any ideas about what could cause that?

I would assume that your chip has an inncorrect pump shot that would cause the stumble. Glad to hear it's going well now, I am getting ready to swap the same parts on to my car so I will have some ?'s for you shortly.

Maybe the TPS voltage is too high?
