yeah the pro-m 'bullet' MAFs were cheap, cheesy, flimsy, etc looking but the other MAFs were made similar to the Ford casting. Univers are very well made, actually kind of heavy.

Can't remember what you had told me about the GM mafs other than they were not calibrated for injectors. I think the reason ford aftermarket mafs are done that way is so that you can install the MAF without having somebody chip/flash the PCM for you or that was the way it was suppose to be.
