what our clients are saying...

 We have been working with Tunewerks' Randy R. the last 3 seasons of Rallycross with our Focus ST, and have really enjoyed this partnership.  The car consistently delivers podium results, is tuned very reliably, and continues to perform to our expectations while on course.  The level of experience he provides, his consistent communication, programming ability, and technical advice, are well beyond the industry expectation. When competing, we truly feel like we have another partner in our corner!

The staff at Tunewerks were professional at every level. Tuning was done remotely, even though we were at opposite sides of the world! Responses were extremely quick, usually the next morning due to the timezone difference. Any questions I had were answered quickly and knowledgeably by Randy R., the Director of Calibrations. The maps were incremental, adding more power each time. Randy gave honest advice about when to stop adding power and preserve reliability. Not many tuners would do so in their pursuit of headline grabbing numbers. I would highly recommend Randy to anyone thinking of a remote tune.

Randy’s programming created for our 2016 Ford Fiesta ST locked in our spot on the 2-Wheel Drive Rally America championship podium! We came from behind in the series after chasing mechanical issues the first five races, but once we partnered with Randy R. we were able to complete every race (and on the podium!) thanks to impeccable tuning and customization specifically to our car and class requirements. We couldn’t have been happier with Randy’s knowledge and customer service!

I wanted to get a bit more power out of the car with an air filter and a custom tune. After researching tuners for the platform, Randy from Tunewerks kept coming up as highly recommended. His instructions are detailed and he answered any questions I had. He had the tune dialed in to my fuel in just a few revisions. There is honestly quite a difference in performance just with a custom tune. At the same time, I know the reliability is still there, as Randy has been tuning the platform for several years now. Highly recommend!

I worked with Randy for over 2 years making changes for different mods and fuels, he is the most experienced tuner I have worked with especially on the ecoboost platform. He tuned my 2017 Focus RS which was bar none one of the best running and most powerful RS’ out there. At my DA of over 7500 feet, on stock motor and turbo I was running between 12.5s and 12.2s, and trapping over 110 mph. The car made a lot of power and ran extremely well. Never had issues with his tuning. If you want someone to take the time to dial in your tune and you want reliability & power - you cannot go wrong with Randy R. and Tunewerks.

Randy at Tunewerks is the best tuner out there for the Focus and Fiesta platform, hands down. His attention to detail and care are absolutely unmatched by anyone else in the game. Not only does it show in the performance, but also in his customer service. He has always been quick to respond and is always quick to explain something to you if you don’t quite understand. He’s all around a great guy and is an absolute pleasure to work with. I will always return to Randy for my tuning needs!

I have been tuned by Randy for almost 5 years now, since my '15 Focus ST had 800 miles on the odometer. It's been 38,000 miles of no-issue, competition winning abuse and the engine feels as tight as a drum. I have only ever recommended Randy to fellow enthusiasts, and I will continue to.

I had Tunewerks carry out a custom Etune on my Mk3 Focus RS and to say I’m delighted is an understatement. From the word go and throughout Randy was extremely informative and demonstrated his great knowledge of this vehicle. Being in the UK the 8 hour time difference didn’t hold the process up either, with map updates arriving within 24 hours of sending the data to him. The car now performs amazingly! And most importantly it's safe! I can’t believe the transformation and it was a great experience to be part of, from carrying out the data logs to getting a say in how the car is feeling/performing. Thanks again to Randy and Tunewerks.

"Randy helped get the most out of my stock RS and brought out all the power Ford left on the table. He was super easy to work with, always responsive, and even helped me months after the tune was finished when I needed an update for the launch control. He's one of the best in the business, a true asset to the community."
