I highly recommend dyno comp in scottsdale they did a great job tuning my car. They are geared towards high end cars but will tune anything and treat it just the same as if it was a $100,000 car. Their shop is very clean and organized and the dyno they use is very well put together. The deciding factor in me taking it to them was they were the only one I trusted to run my car.

here is the link to my post when I got it tuned.
