i recently bought a 07 mustang and it has bbk long tube headers installed. the oxygen sensors are going crazy and throwing all kinds of codes. the car doesnt run terrible but you can tell it needs a tune and cold air intake. my question is if i install a tune and cold air intake will this turn off the check engine light and also help the car run better? i saw a air raid cold air intake and bama tuner combo for 600 bucks? are these decent?
