As I said you run out of calibration.   Exagerated, it's like trying to run
a 6K rpm with the timing set at initial advance.  You can do it but but
it'll be real hard to make the HP.

 I know that upgrading from

Going 730 means going MAP. and the 749 and 730s are the only 2 bar
application redialy available ecms for a v-8.

  Couldn't the MAF data be recalibrated with a prom to measure

Not, by any mere mortals.

 I'm hoping for

Best of luck, might read the archives, and form your own opinion, based on
more opinions then just mine
