Harrison Performance and Tuning, Tucson AZ

The team at Harrison Performance did an excellent job at getting me set up with a CTS downpipe for my GR Supra and scheduling me in for a tune! It was a quick, hassle free experience with great communication throughout the entire process.

Speechless, just… I had an intake and piggy back tune on my A90 Supra; Added a catted down pipe and tune… this is way, way better/faster/my Boxster friends should be afraid.

Richard and his crew did a phenomenal job with my 2015 GTR, did a turbo and fuel system upgrade and it went perfect! Great customer service, attention to detail and communication. I would highly recommend Harrison Performance! Ricky did a a great job with pickup and delivery!

I highly recommend Harrison Performance and Tuning. I called about a tune for my 2020 Supra and he was able to find get me in the same day. Besides the great customer service, these guys are really passionate about what they do. They stayed late on a Friday afternoon just to dial in an already great tune to get me up 400hp. I will definitely be using them when I’m ready to do more upgrades.

My Rs3 has spent a decent amount of time at Harrison and all I don’t trust any other shop in Tucson. Their techs are extremely knowledge and work fast, not to mention some of the best customer service I’ve experienced at any shop. They were able to give me a diagnosis on my car before I even made it home after dropping it off. When it comes to a modified car, Harrison is the way to go.

Great people to trust your prized vehicle with! Richard and his team are very detail oriented! Thanks Harrison team! LH

Harrison Performance is King
I’ve never had another shop be so good at what they do. The customer service is a 11/10, the quickest response time I’ve ever had, and they update you every step of the way.
My 2021 Supra got a new Pure 800 turbo, Harrison performance catch can (since crank case pressure is always an issue with these supras), new NGK spark plugs, my injectors serviced, and compression test to ensure the engines health. They are so responsive, quick and awesome at what they do. Need go fast parts- go to Harrison. Thank you guys!

What can I say, Richard and his team do amazing work and in such little time. This was my first build and Richard was patient in answering all of my questions and moving things around because I kept adding things to the build. My car is an absolute beast and it performs flawlessly. If you are looking for a good reputable shop that knows what they’re doing, Harrison Performance is the place to go!

I took my STI over to Rich to some minor bolt ons (down pipe, intake, blow off valve, and fuel pump). The car came out perfect and exactly what I was expecting. The turn around time was great and the communication they had with me about the car was great! I would and do recommend Harrison Performence to anyone I know looking to get good work done. Thank you guys very much!

Had them take my mostly stock GTR to fill bolt on put down solid power. Great communication throughout the entire process and was more than willing to work with the budget you have to make sure that your money is put to good use. HIGHLY recommend with ZERO hesitation and I will be utilizing their services when it’s time to turn up the wic. Excellent work

The level of professionalism was amazing! They help guide me in the right direction to things I might want later. Shout out to the entire team! They explained about what was done. Richard and Evan thank you for all your help!

I contacted the owner Richard by email asking him for a quote

I went into his shop to meet him in person and to check out the shop.

He informed me that he was very busy! But that he would give me the estimated in a couple of days.

It's been approximately a month with no quote!

Now Richard won't answer my calls or emails

I feel that Richard is a rude and very unprofessional person!

Shout out to Harrison Performance and Tuning for making it possible to get my baby where I wanted her. FBO with Flex Fuel. Extremely happy with the results and the communication through the entire process was amazing.
10/10

Even though our rides aren’t the fastest or most fancy, Harrison still gave us great service and entertained us stumbling around their shop in awe of their big projects. There’s a real value in having legit car people work on your ride, not just dealer techs… thanks for making the supra a little more fun!

Big thanks to you Richard and your great team at Harrison Performance and Tuning! Took my GT-R in for the big differential & transmission fluid service. I had the time to talk with his staff during the service and they are all excellent mechanics very knowledgeable in the GT-R platform and great people in general! They made quick and efficient work with this service! And even allowed me to watch while they took the time to tell me about their process. Exceptional gentlemen! Also spoke with Richard himself for a few hours and he shared with me all his experiences with GT-Rs and other platforms and took the time to explain the details in the full build process for my car, further reassuring me that any future build plans, he and his team are the cream of the crop and where I’ll be going! So as I save my pennies, I look forward to discussing and refining build lists with Richard and the Harrison Performance team in my quest for a 1000+ whp Godzilla! Thanks again, pleasure speaking with you, your wife and the team. I will be back soon!

Contacted Harrison Performance to have some work done to my A90 Supra on 03/13/2023, which was in the shop by 03/17/2023. They go the extra mile to make sure the car is protected while they perform maintenance and pays extra attention to detail, I would highly recommend anyone who needs work done on their vehicles

I’ve dealt with them on two occasions and both went great. Richard happened to have a part I needed, and he wrapped it up for transport nicely!

Best shop around for any automotive performance or protection upgrades! Super high quality work, super knowledgeable and super friendly folks! Can't say enough, if you want your car to shine or go fast, give Richard a call.

Just had some work done to my 2020 A90 Supra. I don’t know much about these cars to begin with but after this experience with Richard Harrison, I have learned a lot as well as the build process was step by step! Details of what was going on and pictures to follow! This man definitely knows what he’s talking about! Thank you so much for such a great experience. I’m already saving up for the next step!
