Dynospeed Racing

Josh was amazing to work with. He did a PPI for me on a 1000hp ZR1. Answered a million plus questions I had. Improved the tune on the car. Car drove flawlessly 400 miles back home. He is definitely my go to for any advice or future upgrades. Highly recommend!!

I had been playing around with possibly upgrading to Hellcat Challenger. I wanted a little more power and a different sound. I instead reach out Josh at Dynospeed to discuss the possibility of making a couple upgrades to my CTS-V gen 2. I picked the car up and it is a night a day difference. My only regret is that I didn't call them sooner. I'm already looking forward to another round of upgrades to squeeze out alot more boost and a whole lot of power. These guys are exceptional at what they do. Give them a call you won't be disappointed....

I highly recommend Dynospeed. When I first went to the shop I was interested in having a Roush supercharger installed and John informed me that was really a ford dealer type thing and even took the time to look up certified dealers for me which their isn’t one that isn’t at least 100 miles away and also told me the ones they offered not once trying to sway me or put down the Roush one. Well ford dealers were gonna be 2 months out so I went with a wipple I purchased and he said just have delivered to their shop. He kept me informed got me in soon after it arrived and installed and back on the road. All shops should take a page from their book on customer service. They are awesome thanks again John !

Thank you John, Josh, and Team: Dynospeed Racing is the only shop whom I trust to work on my ‘14 Shelby GT500–or any American performance vehicle owned by my family. 🇺🇸

John was amazing to work with. John and his team went out of their way to make my build perfect. They also did some extra work without charging. He also made sure with my experience in driving supercharged vehicles that the car was set up and tuned to my experience. If you’re looking to upgrade, repair, retune, or get advice I highly recommend this shop.
