Griffin Built BMW Custom Tuning – Unlock the Full Potential of Your BMW

 Fully Custom ECU Tuning for Maximum Power, Reliability & Drivability 

At Griffin Built, we don’t offer generic stage tunes—every tune is fully customized to match your specific setup, fuel type, and driving goals. Whether you’re running pump gas, E85, flex fuel, or a big turbo setup, we provide a dialed-in calibration that optimizes performance, improves throttle response, and enhances drivability.

  NOTE: To receive a custom tune, you must have either MHD (Mobile Tuning App) or Bootmod3 (BM3) installed on your vehicle.
