How to proper scale injector flow table for SVO 30# injectors I installed my new heads and Fast 90 intake with SVO 30# injectors and need to scale them to get me to the dyno. The car is running -10 on my LTFT's. My fuel pressure is around 62 psi with the Racetronix fuel pump.

Sweet thanks.
I will give this a shot.

30*sqrt({your 62}/{Ford's 40}) would be the
0-vacuum flow value for these injectors on your
fuel rail (is that 62PSI at WOT, or just 62PSI at
idle? You might want to set it for the higher-flow
pressure).
Take that calculated value, divide by the value in
the leftmost column of your IFR table and you will
get the scale factor to apply to the whole table.

The 62 psi is at idle only. I need to make changes to the whole table or just the injector flow table only? Jim give me a call if you could need to ask you a few questions.
