Boost and MAF

I have a single turbo setup on my 87 MAF Formula. What is the best way to add the additional fuel?

my current plan: I am going to add larger injectors (30lb/hr) reconfigure the factory prom for the 30lb/hr injectors. Using the MAF sensor for the additional airflow calculation. I figure the factory mass air can flow about 490hp (crank) before the MAF reaches it's max voltage i.e. max air flow.
This will be about 9psi of boost on my sissy 305ci.
Therein lies the problem, after 9psi I will have need of a different solution. Any Ideas?

I wonder if you could run dual parallel MAFs with a voltage divider and then cut your VE table in half. Kinda like running a 2 bar MAP, you get double the range for half the resolution.

Youll peg the stock maf with a turbo in nothing flat. A larger late model maf would work and youd be able to handle the fuel but then theres no reference for things like timing with the maf. The engine no longer operates from 0-100 kpa so the LV8 wont have much meaning. I suppose it would be possible to tweak it so it does but one of the SD ecms designed for boost would be a better choice as things are referenced for pressures over atmospheric.
