Was just going to say the same thing as JWillis, I wouldn't upgrade both ! either one or the other and then you still in that "Maybe" in pop range. The custom tune you will still pass emissions BTW I did in Mass, The "old" and say old cause still "says" they have addressed their can tune issue, But their old can tune was crap and super rich. The custom tune just leans it out and changes some timing , Nothing that would make you fail emissions. If I go this way again the only thing I'm doing is a tune and the frozen-boost heat exchanger
