    So if problem is not with car or ECM - maybe the $12P NVRAM board in the ECM???

    Thank you! :happy:

    The big reason to go with this arrangement are twofold:
    The 4-bbl intake's open plenum was physically too big and killed air flow.
    As such, using a 4-bbl TBI inherited all the...

    Sounds good, but I'm not talking about factory injectors - they won't fit a FAST TBI anyway.
    Besides they are not low pressure injectors, they are MPI type running 43psi (capable of 60psi)

    That makes sense since the original application had a single 60# injector.

    My setup is firing TWO 74# injectors. So we treat it the same and just scale back the fuel?
