“Dyno-Mike” at 5250 Performance was a pleasure to work with. Great experience end to end. I’ve never done a chassis dyno session before. I hand built a truck from scratch and was looking for someone to double-check the tune and adjust the speedometer. I called about every other shop in the Colorado Springs area and none of them would respond to a phone call a text or an email. Mike picked up the phone immediately on the first call. I told him I was a rookie at this and I was happy that he immediately began to ask me many questions to make sure we were on the same page with the outcome I was looking for. I was very surprised how many questions we had to get through before we could be on the same page. That’s when I knew this guy cared. As with most shops, I had to wait about six weeks to ge

Overall, my experience with 5250 was good, but not without challenges. I brought in an LS swap with Painless wiring and ECU. The team got started quickly, but I felt the ECU was dismissed too soon as the root issue, despite Painless being a reputable brand. After trailering the car two hours, I had to bring down a factory ECU to continue. When tuning still didn’t go smoothly, I was told it was a wiring issue and that they couldn’t spend more time on it. Ultimately, the real problem was an incorrect O2 sensor (internal ground vs external ground style) an honest overlook when I ordered. While I appreciate the effort and understand the demands of this industry, I expected more professional communication and less product-blaming throughout the process.

I have always had nothing but the best experiences with Mike and his crew. Mike has been my go-to mechanic for any task big or small, he is extremely knowledgeable on all platforms. You can tell every car he touches, he takes as much pride as he would in his own vehicle. Every service he has done for me has been done with extreme precision and you can tell the job was not rushed. Mike pays attention to details and gets whatever you need done right the first time! I look forward to doing a lot more business with Mike @ 5250 Performance and will continue to recommend his services to everyone I know. Thanks again for everything Mike!

I had a wonderful experience yesterday at 5280! Mike was super informative and helpful, and he was sure to let me know about all the issues he ran into! They fixed the clutch assembly on my 09 wrx and I couldn’t be happier with the work! It drives so much smoother now!

★★★★★ 5.0 Jonathan Garrison · Oct 2020

Highly recommend! Mike and Ryan are both very knowledgeable and experienced mechanics, with a passion and niche for high performance. The shop runs on schedule and all work is done right the first time. Plus, they called periodically to give me updates, lay out different options to solve specific problems, and guided me on the best solution for my car, my needs, and my budget. Oh, and upon inspection they also found additional things that needed to be fixed now or in the near future. All of this gives me confidence and I know that they take pride in ensuring cars are running their best. It can be hard to trust someone with a prized possession, but they've earned my business and trust on my 1965 Chevy Nova (twin turbo'd and approx. 900 HP!).
