Charles, I am going to assume with that size of injectors that over running your intake manifold is not the issue you are dealing with. What's link say your lb/min are?

As for the water lines to the tb, I would run the car than pull the tb and see if you have any water on the isc.

For those operating temps you need to check to see what it is for 2g, I thought it was 180 so you will be flipping back and forth between closed loop and open loop. I know 1g is 190 but pretty sure I heard 2g is lower.
