Who can I take it to that would have the ability to flash my case I know a coupe Subaru techs but they have an older flash for stage1. Cobb down pipe or? If not a pro tune then cobb v3 or ?
As fas as I know, there are really only 2 scenarios:
a) You either buy a cobb AP (v2 or v3) and just flash cobb's maps and enjoy. Or you ask TorquePerformance (or any other etuners) for a map that you can then download to your AP and flash and enjoy.
OR (if you do not buy a AP, save that cash)
buy a DP and whatever else you think you want to maximize flow, you go see a tuner, and get a opensource protune and enjoy. They will tweak the car for best performance, but you will need to go back each time you need something done or changed etc...
the AP allows you a convenience (unless you live right next door to a tuner of course) that allows you to do changes and monitor your car's system on the fly. It doesn't matter what version of AP you get, some have more features than others and yeah, the 3rd version is nice and implements nice upgrades over the v2 but they both work just fine. But an AP will never replace a shop tune.
I am not sure what you are asking about the "cobb downpipe". Yes the minimum you need to go stg2 is a catless DP.
In terms of tuner shops in the area, I here Brentuning, Granitestatedyno are good places to start unless you wanna drive all the way to boston etc where you will have a bit more options. ... hope that answers some Q's, but continue to read the FAQ's on nasioc!!
