For those using "mass air" FI systems there is a mass air meter before
the throttle body that meters the amount of air being ingested. It and
the computer is calibrated and set for the stock capacity injectors
(let's say 19#/hr). if you swap out the 19s and put in 24# the computer
does not know this. it will continue to calculate fuel needs/injector
pulse width as if you're using 19# injector and therefore you will run
RICH. You can fool the computer by altering the voltage value sent by
the mass air meter.
Our truck engines use a speed density system so I don't know how it will
be affected.

Summitt has the below part number for $200, 24lb/hr flow
rate, says that
"the injectors work best with air meters with revised
calibrations that have
been specially trimmed for high flow rates" What the
sam hell does that
mean?
