I just got back from picking my 2016 BMW X5 M50i up from the tune shop! I cannot describe how much faster and more powerful the car is now! It was worth every penny! If you have a European or an exotic car, check out westtuned for your performance upgrades and dyno tunes! One look at their Instagram page and you’ll know they’re the one for you. They have worked on some pretty amazing builds. Can’t say enough how impressed I am with this tune. This thing is a monster now! They have definitely earned my business for life!
