The Perfect Tune

Who is Cedar Performance?

Cedar Performance are DME Tuning Experts with a passion for 'OEM Engine Management' systems. With more than 30 years combined experience, in conjunction with time spent working for the BMW factory, what we provide above all else is confidence in calibrations. Our DME Tuning Is The Worlds Most Advanced Engine Tuning ECU Software available for BMW, McLaren, Mercedes, Porsche, Audi, Ferrari, Lamborghini, Bentley, and Range Rover.

These days, it is very simple to find an individual who is capable of editing a file and making some sort of performance gain. Unfortunately you do not always know what you're going to get with some of these files. Many times products are under-reviewed, or make very vague claims at what the actual results may be.

At Cedar Performance you can trust and expect our DME Tunes to perform as much like the original software that came with the car as possible while still making use of modifications.

With a focus on what we like to call 'OEM-Like' calibrations, we have developed a suite of DME software for various European makes and models. Our Stage 1 and Stage 2 tuning is designed to be as low-risk as possible, while still pushing the limits of what the stock hardware configuration is capable of.

With these tunes we manage to remain competitive in regards to gains while maintaining factory safety measures and calculations.

Utilizing a large network of sister companies (such as RK Autowerks in the USA) offering hardware modifications and upgrades, we are able to stay on the bleeding edge of software development by meeting the needs of these shops.

What this means for you is that the most complete, thorough, and robust software available on the market can be expected to come from Cedar Performance.
