I inquired about the Revo software upgrade for my Audi. Tyler explained to me in detail the process and what I could expect. He is very knowledgeable about every aspect of working on cars. I was impressed by his expertise as well as having seen his accolades posted on the walls in Quattro Magazine. I would recommend his shop to anyone who is in need of maintenance and upgrades. I live about 90 miles away and it was well worth the drive.
