I just purchased an '07 WRX Limited. I am completely new to the turbo world.
First off, and most important; there is a BCS installed. I know that this part is unnecessary and probably causing harm. What steps do I take to return this back to stock? I don't have the money for a proper tune. The car did not come with a boost gauge so I have no idea if I am over-boosting.
Also, there is a K&N Air Typhoon SRI installed, is this acceptable?
It sounds like there is a blow-off valve installed as well. I believe this is true because my dad’s ’07 STI does not make the pshh sound when letting of the gas like mine does.
These are my main worries about the car. I wish it had been completely stock, but beggars can’t be choosers ( I wanted the leather seats and sunroof )
Any help is great help.
*edit* I joined in Jan 2009? Guess I've been looking to get a subie longer than I thought. Glad it's finally true.
