Injector Number's Needed

[side waz]

Hey guys what's up.

Well I have this posted over in the Skyline section but so far nothing so I'm hoping that someone in this section may be able to help me out here.

Straight up, I was'nt to good at math and as well I'm not even familiar with the equations needed to figure this out.

Now when using SR 370cc injector's in my 240sx KA-T, I found out the safe number to use before a dyno tune was -27% on the SAFC in order to make the SR injector's function like the stock KA injector's.

So my question is, if I want to run GTR 444cc injector's in my GTS using an SAFC whats the number needed to make them act like the stock RB20 270's? Eventually I'll either be using a tuned ECU or Power FC but for now, the SAFC will work fine but I just need to know what to set it at to drive safely before hitting the dyno.

Any help would be greatly appreciated and thanks very much
