Our Testimonials
Shaun, Noah and the boys know their stuff. I have both and old 7.3ford and 5.9dodge. They take great care of both. My (almost factory original) ford had a leaking HPOP last summer. Took excellent care of the problem(s) and gave me a few options for upgrades while it was in there. Left the shop with more than 2x the stock power and an upgraded gearbox to handle it. Defiantly wasn’t a cheap job, but I feel it was well spent and my money went far. Overjoyed with power and reliability. Thanks guys!
All around five stars for sure! The guys were great super knowledgeable. Same day service very easy to talk to great location nice atmosphere above and beyond reasonable prices definitely would recommend them number one in all of Central Oregon.
Through a referral, I found out that Performance Authority works on older cars. I took my 56 Chevy Bel Air in to figure out a leak. The guys at Performance Authority determined that the car needed a new intake manifold. They fixed the problem and the car runs better than ever. I highly recommend Performance Authority to anyone looking to have work done on their vehicle.
Nate dug into my Duramax to replace the injectors and found that the heads were pitted. I’d have to wait a bit longer for parts. The heads arrived and the job began. A couple days later, I was in the neighborhood, so I stopped by to see how the job was coming. Nate had the flu and was out for a few days. Shaun, the Ford guy, took the time to show me the progress of the reassembly and the pitting on my damaged heads. He said they'd wait until Nate returned to finish the job. Read More
