BMW Custom Dyno Tuning – Calibrated for Precision. Trusted by Drivers.
When it comes to tuning BMWs the right way, nothing beats a properly calibrated dyno session. Partee Racing is proud to offer our custom dyno tuning service for all OBDII BMW platforms, led by our in-house Calibration Engineer, Matt Lambert (formerly of Cedar Performance).

One-on-One Calibration from a Proven Tuner
Every session is personally handled by Matt, leveraging over a decade of OEM engine management experience. Whether you're working with a classic E Chassis, a modern G Chassis, or anything in between, we bring the tooling, datalogging, and engine strategy knowledge required to dial in reliable, repeatable results.

Naturally Aspirated or Boosted – We Speak Both Fluently
From factory-spec NA motors to heavily modified turbo builds, we don’t guess — we calibrate. Our tuning process is grounded in real-world data and tailored to your build, fuel, environment, and goals. No canned maps, no shortcuts, just software that works like it was always supposed to.

Flexible Scheduling, Remote or On-Site
Tuning sessions are available in half day or full day formats and can be performed remotely or on-site at our facility. Remote tunes receive the same attention to detail, with multiple revisions based on your data and feedback.

Requirements & Considerations
DME unlocks may be necessary depending on platform. If you're unsure whether your ECU needs unlocking, contact us before purchasing. Unlock fees are not included.
