i went with the sct 3 from brenspeed as well with the c&l cai and they do an awesome job of tunning. i got 3 tunes and everytime you add to your car all you have to do is tell them what you added and they will make a new tune for you. it costs for the tunes if you dont buy from them tho. but my tune from them is dead on i had a pretty awesome poer gain and the shift points r dead on ive got an auto which will oviously be diff than yours but my cherps the tires going into second and third and still kicks hard in fourth with just the cai and tune from them.... and the customer service is great anytime you have a queastion you just email them and they respond with in a day or 2... any money spent with them is money well spent
