You don't have to wait for the tune before you do the CAI and exhaust. Well let me qualify that because I'm not positive about the CAI. I have the Steeda SRI and it has an insert that restricts the airflow enough so that you don't have to have a tune, remove the insert and you need that tune. I'm dying to remove that insert !!!
I've already done my exhaust (2 1/2") with no issues without the tune.
Luke, that might be an interesting question to try and get an answer to and add to the list. When is a tune required? Also the fact that we can't get one yet.
