  • Hands down the best experience I’ve had with a shop since owning my M3. These guys are incredibly accommodating, professional and knowledgeable. Prices are great and the result is amazing. Will be back ASAP for more. Thank you!

  • Can't say enough about these guys. If you love your car like I do this is the place to go. They treat your car like if its their own and meticulously take great care of it. They recommend exactly what you need to keep your car running. Thought my BMW 535 xi had no more life after going to a different BMW specialist, but these guys made my day by making this car back to road conditions. Can't thank you enough! You guys certainly know what your doing!

  • These guys really know there stuff. I high recommend them for anyone who has a BMW with an N54 or any other euro car. They are knowledgeable and have amazing customer service and will treat your vehicle as if it was one of their own cars. I recommend this place 10/10. I won’t be taking my car anywhere else but Peak Performance.

    Josh, Sam and Cole are by far the coolest people I have ever met. They’re always willing to go above, and beyond! I love when they always add a little spice up on my car! The build I have currently is on a big single turbo conversion precision 6266 by Speedtech kit and builder was done by Josh. I live 1hr and half away from their shop and you know what I don’t care because they’re by far the best shop out there for our cars!! These are the guys to go for your aftermarket performance, and maintenance!!

    Josh is a BMW genius! He answered all my questions patiently and worked to find a solution for what I was looking for. If you want piece of mind knowing your BMW is in good hands with knowledgeable staff, look no further!

    Josh and the team over at Peak performance & Diagnostics does a phenomenal job with all my automotive repairs for my Porsche Cayenne GTS. The only shop I work with since I can trust them and they provide exceptional top notch quality service. They absolutely care about your vehicle as if it’s their own, and take such great care of it. Highly recommended! Check them out.

    Honest and talented team of guys that you can trust with your car. Right off the bat you could tell they were polite and professional, and the shop was very organized and clean as well. I would recommend them to anyone else with a BMW.

    This shop was very quick to exceed my expectations. Josh (owner) was awesome to work with and very knowledgeable. The zero percent financing option was a big help and allowed me to do a little more I wanted to do. Thanks again!
