I'm also a Subaru guy that's really considering the leap to a MS3.
I have the Cobb AP for my 06 WRX and while it's dyno didn't look very impressive, it's the curve that really needs to be looked at. For example the torque shifted from 230lbs @ 4200 down to 271lbs at 2900 rpms.
On my WRX the gains were modest when comparing before and after numbers but the translation to the drag strip is were it was apparent. A stock 06 WRX would run 5.4 0-60s with 14sec qtr at 95 where a Cobb Stage II runs 4.8 0-60s and low 13s in the qtr.
Plus there are ton of tuners experience with the Cobb software and products, and will be very familure with the MS3's AP. Some tuners will even offer "mail order" tunes with feadback from data logs, like PDX Tunning so you wouldn't even have to leave your house to get a tune.
