I have a 2011 WRX and want to tune just for an intake. Tips? Might give GST and EQ a call. Can't justify buying an AP.

 

Why would you have just a CAI, I'm not 100% sure if you will gain if not lose power from that CAI. The BoV and CAI have to be the most pointless mod for a car stock or near stock! Good luck, I would try EQ tuning or GST or Fine Line Imports. Wont go wrong with either one, just seems like a waist of time and money!

 

Not sure if this makes any sense, w/o a cbe exhaust it is not even a "stg 1". Why would you want just an intake???
It's not going to yield any real hp difference.
If it isn't CARB legal, a cop can give you a ref ticket.
I guess if you just want your car to sound "cool", go for it...it's your money! The 3 shops mentioned above will do a good job.
