I had the engine built by a reputable builder. However he did NOT know it was going in a TBI vehicle (he's more racing/classic oriented) and I didn't know the difference, so the cam is just a bit hot for this application. It ran, ran pretty damn good, but would not run/idle/run to my satisfaction.
Yep computer was definately better and easier in this case. I had the same issue with my last motor. Took a month of sundays to work that out.
