Dyno pulls with some real time troubleshooting
Took my son and his prized '91 Volvo 240 in for some post turbo-swap dyno pulls. The Miller Mountain guys did several extra pulls and helped us diagnose an ignition cut issue we were having (intake hose collapsing under high boost). Would never have found the issue without them. We had a blast and ended up with almost double the stock HP!

My Dad's Other Baby
Brought my Dad's 1970 Corvette in for service since it hasn't been on the road for at least 17 years. Art walked us through all off the repairs that needed to be made and worked with us with the finances. There is still work to be done, but it is great to get her back on the road again

Very professional approach to customer service
Took my 2011 Shelby GT500 to Miller Mountain for a checkup and get an idea of the horsepower at the rear wheels. Very happy with results. I was fortunate to take the Mustang to Art and logan, because during an inspection of the suspension, they discovered a leak at the main seal or possible from the oil pan. In as much as this Mustang is a garage Queen, only 7800 miles, it's still under the warranty from the dealer. So, I'm taking it back to be repaired. The warranty expires on October31, so I want to thank Art and Logan for discovering this problem before it cost me an arm and a leg to repair. Great experience for me. THANKS, ART and LOGAN, and the great folks at Miller Mountain.

Great work
I took my 2018 mustang to them at first to fix the mess that another tuner made. They did an excellent job of fixing the issues that were plaguing the car and also installed headers. The car was running better than ever when I got it back but it had this weird rattle under acceleration that no other shop could identify (it was there before I brought it to them). I dealt with it for about a year before bringing the car, again, to Miller Mountain who were able to identify and fix the issue. Now the rattle is gone and the car is running great. Art was a pleasure to deal with and his team did an amazing job on the car.
