MAF scaling when resizing injectors

I just upgraded from 42lb lightning injectors to deka 60lb injectors, and entered all the injector data from the references pages. When I updated the AHISL, all values in the FN036 MAF curves scaled up around 30%. I dialed in the MAF and now they are around 8% higher than they were on the 42lb injectors. This means the RAW MAF is about 25% lower than it was.

Fuelling is great, I have no errors over 5% and most within 1-2%, but the load is now less than 1.10 under boost, where it used to be in the 1.45ish range. Have I made a mistake somehwere, or is this normal with larger injectors?

If it's normal, what should I do to compensate for load to get into the area of FN2200 borderline Knock where I should be in while in boost?

Thanks for your help
