Why Bosch?.  The stock MAF is 250 and the late MAF is 496.
That is way close enough that your not over the top (and if so it's too
close to count).
OK, on the scalars, then what does need changed?????.

| Hi Bruce:  I am not giving up yet on looking at a Bosch (For Porsche 928)
| maf that is supposed to be larger than the GM application.  You would not
| have to use a translator, just re-scale the settings in the ecm.  It
| shouldn't matter since the ecm uses LV8, not actual grams/sec for any
| calculations.
| It would be nice not to max out the MAF at less than 5000 rpm's!  Some
guys
| I have talked to max out the maf at 2500 rpm's!  (Jason!)
