Adjusting 84 vette fuel pressure?

[nelson84]

I bought an x-ram with 2 inch injectors from a guy on ebay. When adjusting the fuel pressure do you just adjust the rear injector or both? It came with the little bent tool to adjust the fuel pressure.

First I have to order an 85 fuel pump.

The Regulator is in the rear TBI. There's tons of info on the Crossfire Injection Forum.
