Our Story

UMS Tuning has its humble beginnings by the founder Tony Szirka getting bored with dealership work and being more and more enthralled by the aftermarket performance industry. Being involved with personal projects since the age of 13, it was a logical progression to do the things he enjoyed as a professional. After moving to Phoenix in 2002 and working at a Porsche specific shop for two years, it was time to take the plunge. August 1 2004 we received the key to our first location in Tempe near University and McClintock. As we quickly grew we needed to relocate to a larger shop within a year and a half. The next location was also in Tempe Near Curry and Miller which was home for another year and a half. In early 2007 we acquired Apex Motorsports of Tempe adding two more lifts and some long standing accounts with some choice vendors.

September 2007 we again moved to our current location in Mesa. We have been growing and adding services and skilled team members ever since. Our goals are simple. We want to provide the best possible service and experience we have to offer to each and every customer entrusting us with their pride and joy. We understand your projects are more than just a car, they are an extension of your style and performance needs, it would be a disservice to treat them as anything less. We appreciate our customers patronage and work hard to create long standing relationships with them. We work hard to not rush projects and to deliver the best product possible.

Horsepower Wizardry...

“If I could give Tony and his team more stars I would. Incredibly knowledgeable, super professional and beyond helpful. After having bad experiences with tuners/shops in the past I began the undertaking of building my car on my own. Although I enjoy doing so and learn a lot, it’s comforting knowing when my car is at UMS it is great hands. Stoked to have my build back and making power (even though Tony is not satisfied). On to the next stage of this build but I will be back when I’m ready for more of horsepower wizardry from the boys at UMS! Thanks fellas and lady”

Great experience...

“I always have had a great experience with UMS, had multiple cars tuned with great success. Had multiple mechanical failures, of which when modifying vehicles can be expected, and had amazing support from Tony both on and off the track at the courtesy of his time even though the failure was never the fault of the shop. Always my first recommendation for tuning in the valley.”

Great shop, good people...

“Great shop, good people. The staff is knowledgeable and answered my long list of stupid questions. Super fair pricing. Reliable tunes. Have had multiple cars tuned here, my vehicle and customer vehicles. None of those vehicles have had any issues and because of that I’m constantly recommending UMS to everyone. When describing what’s been done to one of my vehicles you can hear me saying how there is only one shop in town that touches my cars and that’s UMS. Thanks again guys, I’m looking forward to the next time I bring a car in.”

Nobody better...

“5 Stars for Tony and UMS. Nobody better and the generosity of his time and knowledge is second to none. Can’t count how many times he’s been willing to help people, me included, on and off track when we needed support or trouble shooting issues.”
