Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Pro-Flow...is it worth it?

Figured I'd relay my recent experience with the Pro-M MAF. I finally got mine installed tonight along with an intake pipe and big ole K&N filter. Had to take the Pro-M back off and put my stock MAF on because it ran like crap with it on. Stalled anytime I came to a stop, and when I hammered on the gas it sputtered and jumped. I guess if you've got an AFC you can adjust it but for now mine's off and will stay off until I either find out if SPMotorsports will take it back or I'll hold it until someday that I actually get a AFC.

What a bummer about your pro-m although it's not too uncommon of a story.
Unfortunately, they really seem to be hit-or-miss w/ the contours. Some choke, some kick arse.
