About Us

  • BrenTuning, LLC is a performance automotive facility that was built on a team platform of very unique individuals with vastly differing skill sets and knowledge bases to cover all areas of performance, racing and repair. From our sales team to our in-house calibrator and lead technician, each member brings forth a long history, portfolio and a wealth of detailed knowledge in repair and racing with all the vehicles platforms that we support. When we are not at work we are at the track testing and supporting our worldwide racing vehicles.
  • From general scheduled repair of all modern cars (with a specialization in performance / racing cars) to a custom fuel system upgrade for a race ready BMW M3, or deep diagnostics of a 800HP 4 cylinder engine, our team can tackle the project and offer you a solution. While we focus on performance, we also do routine maintenance and OEM level repair work. We invest in all the latest tooling and diagnostic equipment, along with OEM factory scan tools for the cars we service. We also have rental cars on site.
