    go to Cobb's site, and look @ the map notes for the tune you would be running, it's all explained there.

    Depends on the dyno as different dynos will read different amounts, and are you asking about whp or crank?

    Anywho, if you want an idea of what kind of difference there would be Cobb has their test results right on their website:

    Subaru WRX / STI Stage2 Power Pack

    I assume you were planning on the Cobb stage 2 map since you said "AP."

    It would all depend on the dyno you would use as well. You're probably looking around an averaged 275hp to the wheels at Cobb Stage 2 OTS.

    There are two stages.. stage one is a completely stock car with a tune, stage two is a car with an aftermarket downpipe and a tune.

    Stock would be stage zero? The tune is the most important part, hence, stage one tune.

    The best part of the tune isnt so much the power increase but the power curves improve and you will have a smoother acceleration. My stock tune always seemed lumpy if that makes sense, when you floored it and reached full boost you could feel small bumps in the acceleration. Once i went stage 2 (torqued performance) that all went away and the car doesn't choke as bad in the top end.

    I tried several tunes and for me Cobb stage 2 was the worst, perrin was a good middle ground but the FP tune was clearly the best.

    Your gonna have to wait though, I spoke to COBB the other day and theyre just now starting to work on the maps for the 13's, unfortunately that means both of us have to wait :/
