mjchip,
I have a 87mm Pro-M MAF with a 100mm Densecharger. I haven't had it dyno'd yet becasue I am waiting for my long tube headers and cat'd h-pipe to go on this Tues. However, I can tell you that the Pro-M matches up with the flange of the Densecharger better. If you take your Densecharger out and leave the stock MAF attached you can look down the tube and see a HUGE overhang where the two pieces meet. If they don't line up correctly then it's actually more restrictive that the stock airbox/MAF setup.(w/o the intake silencer) After I installed the Pro-M I let the computer reset overnight and took it out the next day. It definitely felt and sounded like it was breathing easier. As far as power increase, I'm not sure I have enough miles on it yet to allow the computer to adjust. It idles a little more irregularly with the Pro-M also. But, I only have 1800 miles on my car and I have a long way to go before it's broken in, so all this could change once that happens. It's not a cheap mod. If I were you I would add the Steeda timing adjuster first. It's more bang for the buck.
