So I failed emissions. I have a C&L intake and a Brentspeed 93 tune. Do I have to put my stock intake back on and go to stock tune, or can I just go to stock tune and be ok with my C&L on? I heard the C&L let in too much air it needs a tune or a check engine light will come on or something. Good advertising if you ask me.
