I just have a few simple questions here today. One, if I were to get a K&N Typhoon Intake <http://www.knfilters.com/search/product.aspx?prod=69-6546twr>, would I need a tune? Could it be tune from an access-port? Or does it have to be from a dyno? Also, I have a cat*delete pipe that I'm looking to get bolted on to my car. But same question, do I need a dyno tune? Or would it be easier for me to use an access-port? I guess the main subject here is can I tune my car, using an access-port, to fit a cat*pipe and an intake, or does it have to get a dyno tune?
