Tony is an amazing tuner. If you are looking for someone to tune your build look no further. The results speak for themselves. I am left with torque/fuel economy I didn’t know existed and a super smooth powerband. It blows my mind honestly.

Tony, Cuban and the entire team at UMS are top notch. I spent the last two years meticulously building my car and wanted a tuner that would align with my expectations - UMS did just that and then some. Their professionalism and expertise began early on while exchanging basemaps and datalogs to get the car dialed in and extended through to the day of my tuning session. A few issues arose while on the dyno and the guys didn’t miss a beat - got things resolved efficiently and proceeded to exceed my power goals. Highly recommend UMS - thanks for everything guys.

The most unprofessional company I have ever seen. Knowing weeks out the type of vehicle I wanted dyno'd, they finally realized they didn't have the wheel adapters after waiting 6hours in line. Save your time and money and go somewhere else.

Hade an excellent experience. I would highly recommend UMS for tuning and specialty services. I am very picky and particular about my vehicles. I put an incredible amount of time and money into them and when it goes to a shop I want it respected and taken care of. They took in my race car and took exceptional care of it. They are top notch professionals. Very accommodating to my time and efforts. They offer excellent feedback, service, and ideas. We had some issues with the vehicle pre tune, and they had it repaired next day and tuned to perfection. The car makes an incredible amount of power thanks to this great group of motor sport geniuses. Service was so good my other truck goes in next week with total confidence.

Called to receive quote once, they said they would look into it. Call back several days later and they say that’s not a “tunable” car.I told them I simply need parts installed and no tune. Funny thing is they have a picture of a Hyundai Tiburon in the google photos.Just a heads up for anyone that has a Hyundai even the N line they won’t touch.

I had my evo X tuned at the beginning of the year by UMS and was a great experience. They were very knowledgeable about everything evo which helped. My car has simple bolt ons, nothing big, but just wanted to get a good reliable tune and they made it run so perfectly and drove night and day difference. I will back in the future for a re-tune with more bolt ons

Amazing shop with one of the best tuners in the country. They are the only shop I'll allow to tune my cars!

Knowledgeable tuner and does a wide range of cars. They were able to sort out some issues I was having with my swapped Miata which most shops would not touch.
