Harrison Performance & Tuning

Crazy nice and professional crew at this place. I can't wait to have my car tuned by this crew. Their shop/facilities are very nice, and their ceramic coating and protective paint film looks better than any I've seen. Amazing attention to detail!

Excellent service including great communication, fair price and my car looks outstanding! Family owned local business that I highly recommend supporting. Richard and his wife Melaney were easy to work with, no pressure and good follow up and education about how to care for my car. You can tell they care about keeping long term customers and not just one time service.

I had some work done performance wise for my F80 M3. Shop is very responsive and very knowledgeable about performance car. Another time I had issue with my oil pan plug not torquing due to last dealership over tightening the bolt. The owner had me come in on short notice and got it sorted without having to replace a new oil pan. They do a lot of work with GTR/Supra and Exotic. I wouldn't trust any other shop for performance upgrade here in Tucson. I know a few of my buddies with GTRs also only go through this shop.

Came in to check out of my aftermarket exhaust was loose. The guys at Harrison jacked my car up for free and gave me a free diagnostic. Other shops tried upselling me and quoting me differently. Honest and friendly people, 10/10 would recommend

Took my GTO in to have engine modifications. After a year or so they call me to tell that my car caught fire on a tuning drive and is totaled. They tried to blame the problem on a faulty part. To make long story short my insurance company totaled the car. I bought the car back and foolishly had these guys rebuild it. 4 years later I got my car back - it lasted 3 days. Harrison had to rebuild the engine, this time they paid for it. Fast forward to 2022 (about 6-years after I first took the car to Harrison - they were SPS back then). The hood latches failed and the car sustained body damage. I took it to a different shop and asked them to go over the car to see what Harrison actually did. They came back with a long list of things done incorrectly. Things like No oil catch can so oil was spraying in the engine compartment; no catalytic converter; exhaust connections leaking; regulator/fittings leaking; 3+ loose bolts on each side rear axles; tires rubbing the fender; only making 3 psi, s/b 10psi from tune; and the list goes on and on..... They did a real "hack" job

5 Stars all the way around, Richard, Ricky, and the entire Harrison Performance team were beyond great! I flew in from Texas to purchase a GT-R from a local seller and he highly recommended Harrison Performance, I purchased the car and dropped off with the team and had quite a few items done ranging from a full interior upgrade to engine performance and tuning. Not only that Richard accommodated my car in his shop few nearly a week while I had a transport company pick it up to ship to Texas from Arizona. After I took delivery of the car Richard coordinated a call with Ricky who walked me thru the various ECU maps and all the fun part about having a GT-R. Their customer service is TOP NOTCH! I highly recommend Harrison Performance and would not hesitate to take my car back to them.

After buying my very first GTR in September of this year I fell even more in love with the car than I had ever been before! Brought it down to Tucson and met Richard over at Harrison and talked to him about upgrades I wanted to do to the car and how I knew nothing about the car mechanics wise at all! Richard answered everything single question I had and made me feel 100% comfortable modding my car! Even though at times I know I was a bit annoying haha. Now with this 615 WHP monster I can have a ton more fun and have the true potential of the car unlocked thank you to HARRISON! They are definitely the GOTO shop in AZ for anyone having any kind of work done on a GTR!100/10 AMAZING SHOP!Also after walking through there shop and seeing the plethora of different cars they have in there If you need anytype of performance or tuning done to your car make sure to give them a call!!!!!!!Thank you guys so much for making me feel comfortable and educating me more on one of my dream cars!

Got my 2020 wrx tuned here the other day along with a few parts installed, even though I had the least expensive car there , I was well taken care of! By subie GOES!!! Thanks GUYS!!!

I highly recommend richard he's a great guy. He's been in the industry forever he has a machine to tell you how much horsepower they work on all vehicles in the race vehicles in Tucson

I hired this company to do performance modifications to my engine. They managed to install the new, custom cam shaft incorrectly, then had the gall to charge me an additional $6K to get my vehicle back on the road. I do not recommend this company.
