another z32 MAF + SAFC question

[SloS13]

Ive been running an SAFC with the stock MAF for a while now with 370cc injectors (-27%) 5 in, 5 out

I just upgraded to a Z32 MAF and changed it to 1 in, 5 out.

My question is....do i need to change my -27% to something different now, or does the safc handle the MAF change seamlessly?

I made the mistake of upgrading two things at once. 1)MAF 2)Wideband...and the wideband is saying that im running like 16:1-20:1 at boost and the car IS running like crap..so im not going to drive it until i get this figured out. I cant be too sure about the O2 reading, because this is a brand new O2 setup that i don't trust yet
