John Craig retired many years ago and then proceeded to open Limit Engineering. I think he worked for Garrett turbochargers previously. I used John when he was still located in the Outer Banks of North Carolina before he moved to Arizona due to repeatedly having to close because of hurricanes. He's got to be well into his 80's by now. Sad to see so many of the old business owners retiring and turbo Buick owners dying off. What a great guy he was to work with.
