They are $595 new if you buy a used one it will only save you maybe $50-100, and then unless you meet up with the person you will run the risk of it being married already.
On another subject I didn't quite understand I you were going to buy an access port or have it pro tuned to stage 2. From what I have seen and heard, unless you are going to BIG numbers(400+ whp/wtq) everyone seems to love the access port. Mainly for all o the functions it has, even though it is more expensive than the average pro tune. I personally am about to order the cobb stage 2 package coupled with a catless up pipe and K&N short ram intake. Hoping for the same outcome of a nice little growl at idle and cruise and then a real head turning for spirited driving.
You and the OP need to understand that when you deviate from the specific parts indicated for the Cobb off the shelf tune, you should get it protuned at that point. When you get the short ram and catless up pipe, at that point you should be protuned imo for the safest and best results for the mods you put on your car.
