Flooding out after a Walbro upgrade

I had the car running for about 1000 miles (engine break-in period) on a stock TII fuel system, then, I upgraded the fuel pump to a Walbro and the secondary injectors to 720s. The MT still has a basic map on it, although it has been toyed with a bit by a tuner friend of mine. The tuning was done on the old fuel system.

I cant start the car with the new fuel system componenets. The car is behaving exactly as a flooded engine does. I crank it over, and the thing floods right up, and wets the plugs.

What do I need to change to get this thing to fire up?
