So the car has had a weird idle issue since I bought it. When ideling it revs up and down, up and down. It used to die sometimes too. It has an old pro-flow MAF sensor.. I've heard other mustangs having this issue as well. Do I need to upgrade MAF or is it the calibration of the pro-flow?

Unplug the MAF and see if it clears up. That will let you knoiw if thats the issue or not.

Since its a procharger I am assuming its a blow thru MAF setup ? Where is the MAF located in the system ? any sharp bends before or after the meter ? post pics if you can , sounds like turbulence causing the MAF signal to bounce , best way to fix this is a HPX slot meter in the middle of a 12 inch or longer piece of straight piping and retune with that setup and make sure you maf is after the intercooler and the blow off valve is before the intercooler
