yesterday i went and made a downpayment on an 03 wrx. hopefully ill be picking it up tomorrow once my loan goes through. it has a 3 inch turbo back exhaust, cold air intake, and bov. should be a bit of a step up from the 94 celica i had before lol.
my question: ive heard that with a cold air intake on a stock tune causes you to run lean. is this true and if so how can i fix it?
