I've trying to doing my research and i can not find an answer.
I've have a 2011 STI with an after market Subaru exhaust. I have in my possession a COBB Air Intake with Box and COBB Exhaust.
My question is: If i in stall my new COBB parts, is it really necessary to have the V3 Access Port.
I've been told if i don't tune it with the access port and i put the parts on it can hurt my engine or worse. Is this really true?
