About ACR Performance Tuning

At ACR Performance Tuning, we’re passionate about unlocking the true potential of every vehicle we work on. With over 15 years of experience in the automotive industry, we combine mechanical expertise with the latest ECU remapping technology to deliver results you can feel from the very first drive.

Our journey began with a strong foundation in mechanical engineering, with over 8 years of hands-on mechanical experience building, repairing, and maintaining vehicles of all makes and models. This in-depth understanding of how engines work gives us a unique advantage when it comes to safe and effective tuning. For the past 4+ years, we’ve specialised exclusively in ECU remapping and performance tuning, helping drivers across Essex, Hertfordshire, and beyond transform the way their vehicles perform.

What sets ACR Performance Tuning apart is our commitment to quality and personal service. We don’t use generic “off-the-shelf” maps. Every remap is carefully tailored to your make, model, and driving style. Our tuning files are dyno-proven, extensively tested, and applied using state-of-the-art tools, ensuring that your vehicle receives a performance upgrade that is both powerful and reliable.

Whether you’re looking for more horsepower, improved torque for towing, sharper throttle response, or better fuel economy, we provide a customised solution designed around you and your car. And with our strong reputation for professionalism, honesty, and results, it’s no surprise that more and more drivers choose ACR Performance Tuning to deliver the upgrade their vehicles deserve.
