I knew it. I found this data on the mafturburner website...

The default setting for the DIP switch is SW1 ââ?¬â?? SW4 ON. This will scale a MAF sensor output of 0-7Vdc to the full input range of the PCMââ?¬â?¢s A/D input of 0-5Vdc. This setting will only be used under the most extreme circumstances. If the unit is installed with the DIP switches in the default configuration and tuning changes are not made the car will be dangerously lean and may not run at all. As a general rule, do the LEAST amount of scaling possible for your application. Remember that the more you scale the MAF curve down, the more resolution you give up in the low-flow portion of the curve and that this may affect driveability.

It scales pretty severely also. Check out their settings...

Code:

Vin to Vout - Scalar Value - HP ('03 Cobra with stock 90mm MAF)
5V to 5V      1.0000000      545
5.5V to 5V    0.7635203      714
6V to 5V      0.5941677      918
6.5V to 5V    0.4714800      1156
7V to 5V      0.3804597      1433


This could all be done quite easily with an op-amp. Hmmmm...
