I know there was some talk before about which MAF is best to use with the SCT package.

from the mouths of SCT:

Quote:bela, a GT MAF should be plenty for you car anyway. For the Focus this isn't really a huge issue like it is for the V8s. For those you have to go to Pro-M or something, and those are different calibrations from MAF to MAF, making it real hard for us to send a mail order calibration that works right the first time. The Ford MAFs are very consistent from unit to unit, so we'd prefer to use one of those and extend it's range. Since a Lightning MAF is good up to about 450rwhp you should be able to find a Ford MAF for 4 banger use

If the car will be dyno tuned then the Pro-M option is also perfectly viable. They are good MAFs and are consistent from run to run, just not between MAFs.

looks like Ford MAFs are preferred for their consistency, while a Pro-M will suffice for dyno tuning.
