I would run the stock MAF until you change the injectors. When you do just get a pro-m 73mm, 76mm, 80mm, or whatever. I don't think the MAF is a big restriction on your setup. The most important thing is to get one that is properly calibrated.

How is a stock MAF not causing a restriction on that setup? Pick up a 76mm C&L with the correct sample tube. That way when you upgrade injectors, you can just swap the the tube...not the whole unit. ![[Wink]](wink.gif)

Yeah! Heads and intake not restricted by a stock,lame-ass 55mm throttle body,whatever!
Something else you can do is use a later model air meter from a 94 or later stang or a Mark 8 air meter.Just swap in your 19lb sensor.
