Steeda Cold Air Kit, Pulleys and Borla exhaust

[scothran]

I just ordered the Steeda cold air kit and under drive pulleys. I have also installed Borla Cat back exhaust on my car last week. I was wondering if i need to install a new mass air flow sensor? An also do I need to put a new chip or get a programmer to get the most out of these bolt-ons?
