Does '93 70mm Cobra mass air meter have interchangable flow tubes?

Putting together a 347 and just now going to mass air.
The 70mm cobra unit is calibrated for 24# injectors, correct?
I figure I should run 30#'s so can the stock '93 unit be altered?

Even though the 93 cobras came with 24 # injectors the mass air sensor is caibrated for 19 #ers and the ecu alters the signal. You would have to change the black box out to one calibrated for 24#ers or run the cobra ecu.

My pro-m mass air meter is calibrated for 19# injectors but I can change the flowtubes out to compensate for larger injectors.

I have a A9L cpu & meter from a '93 cobra, I thought it was calibrated for 24#'s?
So I guess I need a new meter, 19# injectors are not gonna work out I don't think.
