    Yes, but you'll need to acquire the required "Fuel Injector Information" parameter values:

    Thanks. I thought it would be easier for a Holley TBI unit. I don't know the injector sizes of this unit.
    What I know is that the 305 GM unit uses injectors with 54 PPH flow rates and are low impedance.
    Is this enough Information for you to help me with this? Thanks.

    I don't know anything about those GM TBI fuel injectors. Look at the "Fuel Injector Information" parameters in Engine Parameters. You'll also need the Injector Off Time values.

    OK thanks. My problem is I want to use this car as daily driver, so I would go with a 2 barrel TBI unit, and tune it with my Holley ECU for a better MPG. Thanks a lot. Martin
