Re: MAF BLM based tuning

Bruce ,
    With that being the case why would I want to trash the MAF in favor of
MAP for my future forced induction application?  I know that upgrading from
a '870 to a '165 would increase my serial data rate but what would I gain
from a '730?  Couldn't the MAF data be recalibrated with a prom to measure
greater airflow than it was intended to measure stock?  I'm hoping for
500-550hp and would like use the MAF computer in the short term.
