UMS Tuning, Mesa AZ

Attention to all JDM SELLERS AND SHOPS. Do not sell them any used engine parts.they will you rip you off sold a good running motor with a proof of video compression claiming engine is bad no compression, refund 1500$ or take the motor back we lost over 1000$ in shipping for a good motor.

Recommended only what needed to be done. Gave honest advice. I'd recommend this place to everyone

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.

Be aware, they will rip you off they are real specialist in ripping you off do not bring your business there, there is alot of other tunners shop in town dont waste your time.most of there reviews are fake do not go there.

Scammers all fake reviews please do not deal over charged me rude and will charge you 1000$ of $$$$$ for a 100$ job.please do not go here for any kind of business.

Over charged and over priced they take advantage of people who dont have much information on there cars.

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.
