I've been going to Dyno Tune for years. Randy and Scott are great, I know them very well. I mostly work with Randy. I don't know anything about cars, and I feel like as a woman, other places might try to take advantage of me. These guys don't. They are honest, reliable and fair. They always provide great customer service. This is a busy shop, so make an appointment to get your car checked out. I highly recommend their services. These are really nice guys.
