Unlocked/Unmarried tuner with preloaded custom tunes and cold air kit tunes. Bought this programmer off another member to turn off the rear 02s as i have o/r pipes on my car. Decided to have the cats put back on to meet track and autocross noise restrictions. I don't see a need for it since power isn't a concern for me so id rather put the money into other mods. Price is $270 shipped Obo..(Will be ready for sale this saturday)
