Injectors changed form 26 to 30, IFR table?

I changed out the stock 99 injectors for SVO 30, how do I make the correct changes to the IFR table?

multiply the IFR table by
(30*sqrt(58/43.5))/26.4= 1.312

how is your duty cycle at 6000rpm with your current setup? i'm getting 20-21ms@6000rpm with a dinky cam, so i'm wondering how a much bigger cam is doing.

Keep in mind that your stock injectors are rated at 26lb @ 58psi.
SVO 30lb injectors are rated at 30lb @ 45psi.

Those SVO 30lb injectors in your car flow (IIRC) 36lb @ 58psi.

I already switch out to the SVO 30, I never did checked the duty cycle.

Are you sure that all I need to do is multiply my IFR table by 1.312?

Thanks for your help Man
