Did you break the cap on the master throttle body so you can manually adjust the fuel pressure? If so, I have a question about the regulator. Can we speak possibly?

No mine is factory stock original PSI, there is another youtube channel @Joe's Crossfire Injection Garage he might have some input on adjusting the PSI.

Could you help me with where the vacuum hoses on the TB go? I just bought one and the drivers side TB is not connected to anything

[@dennissmith9577]

Rear TBI the outer port is MAP sensor, inner is air cleaner Thermac system. Front TBI the outer is AIR diverter valve, inner is EGR solenoid. Center port on both TBI's should normally be capped and are only used for balancing.

Did you add in the thing to check it on the pipe

[@HorseshoeBeach]

Yes I built the test harness myself from parts.
