This might be a little late, but There is a shop off Copans called Lashway Motorsports. They deal mostly with American muscle, but there is a guy there by the name of Josh who is a car genius. I used to live in Miami (brother still does) and we only take our cars there. They do amazing work over there...and they have a brand new mustang dyno
Just tell them Jonathan sent you...they will remember me for sure!
