I appologize if this material has been posted else where, I've looked through the stickies and tried working through the pages for DP info, but I get a little confused and lost. This is my first Subaru, turbo'd car, and never have I had a "tuner" car. (sorry for that coined term) I've had and built many pre 70's cars, but those all seem to be a cake walk compared to what I am now interested in with my Subie. So please any information, tips, suggestions, or any FAQ's you can steer me to I greatly appreciate it. I have a stock '13 WRX, first mod was to get a Cobb AP and go from there.
Ok to my question
With a DP, are there any brands that stand out beyond others? I wanted to stay with a catted DP just for possible emissions testing. BUt from what I read its easy to just swap in the factory one for testing. As I dont live anywhere that has testing at this time, I am planning on moving back to Cali in a few years. If I go with a non catted DP, what happens to the O2 sensor? are they plugged off? how are they corrected? Does the Cobb AP has a reset code in the sensors are not plugged in or reading?
Next whats is the difference/bennefit to a divorced wategate and non? I saw something about Bellmouth, but Im not sure if that aplies to a stock turbo or not.. Any help on information would be greatly appreciated. Im just trying to get as much knowledge as I can.
