Love to hear the racing stories from a vw enthusiast's viewpoint :) Its too bad the diagnosing these problems is so easy with aftermarket efi, yet the half mechanical/half efi cis systems take a little too much effort to convert.
Before you dump the car it may be something to consider. After all, we know our cars won't sell for enough to make it worthwhile. May as well mess with them and make them even more impossible to sell. Megasquirt was the efi I went with long ago and it worked out well for my needs.
