They are local to me and I use them for dyno and tuning. Great guys, awesome shop.
They do all the dealer performance options for Downs Ford. Downs is a big east coast Ford Performance Dealer. Most times there are 5 Shelby 500's there, new with stickers, and 30 mustangs outback for tune. One month backlog for tuning I'm due up in two weeks. They did my Lightning too. I wouldn't trust anyone else to tune for me. Yes they have NA and FI Focus experience.
