R.Spec Tuning 2511 North Hayden Island Drive, Portland, OR 97217

"Riley really knows how to smooth out the power curve and unlock your cars true potential and customize it to your liking. He explained everything he was doing and left me with great results. Highly recommend!"

"My experience at R.spec was amazing. Riley was very kind and very knowledgeable/informative. Someone like myself that has complete no knowledge on cars especially cars that requires tuning, he took the time to break down everything he was doing and looking for as he was working on my car. I truly appreciate the time and the professionalism he provided. I will most definitely be going back again for all tuning needs and more. Thank you Riley, I appreciate it so much"

"Tuned my 2004 Subaru wrx. He was awesome nice and friendly. Taught me a lot about my car that I didn’t know of, made the car feel way better, it was a night and day difference on what it ran. Would recommend him to anyone"

"Rspec does a great job. Heard of them through multiple friends who also had great experiences with their service. He does a great job breaking down what goals he is trying to reach with your car and will listen and answer all your questions. He also answers any questions days, weeks, months after the tune which is great. Will definitely go back for any other projects."

"Drove all the way from Seattle and couldn't have been happier with the results. Would definitely go again. Riley was amazing to work with! Super informative and walked me through all the changes and all that was going on. Gave mini lessons about how it all works together. I was recommended here by others and I will continue to join in on recommending R.Spec for your car’s needs. Everything went as smooth as can be, there was a small little problem with my car and it was already fixed in less than 5 minutes. If you have questions about your car just ask, Riley definitely knows his stuff."
