Ok guys, I have been out of the loop for a little bit with the stang world. Going to be putting on a Vortech S trim on the cobra and found out the other day that Pro M went under. I have a NA 77mm on the car right now and had wanted to send it in to get redone with 30lb's and SC but I guess I cant. What else can I do? Should I get the 42lbs and a lightning 90mm and get a custom chip done? Please let me know... Thanks.
