What Our Customers Say
"I trust these guys"
“Fantastic performance shop!! Miller mountain went over and above to ensure my truck got tuned properly. I brought my truck in with a trash remote tune and they took the time to dial everything in to perfection. Super friendly service and very easy to deal with. I trust these guys with my vehicles and will be back for all my tuning needs in the future.”

"Friendly and professional"
“First time customer here and these guys are the real deal. They installed a cat-back exhaust system on my 10th gen Si. Mr. Miller and his team were very friendly and professional. I am extremely happy with the work they've done. The shop is clean and the waiting area is cozy. I highly recommend this shop!”

“Had headers installed and engine and transmission tuned. Would like to thank Art and Logan for the excellent service and workmanship. These guys definitely have the knowledge and know how to get things done right and in a timely manner I would recommend this auto shop for repairs and high performance projects.
