MAF and Boost
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.

Easiest way- FMU
Best- change ECM to either a 1227730/749 and run the $58 code in prom they you will have control of fuel and spark under boost.
or if you have alot of cash......buy a Aftermarket EFI from Accel/fast/holley/bigstuff........

Your maf will work. There is a guy on Iroczone.com Who has a supercharger running 13 lbs of boost and he still uses a stock maf sensor. Just need to get the proper tunning done to it.
