Keller Performance ECU Tuning for BMW F91/F92/F93 M8 2020-2025
Keller Performance ECU tuning is developed with and by DME Tuning, combining their proven ECU calibration expertise with Keller Performance’s system-based approach to performance engineering.
Each calibration is expertly developed and meticulously refined to deliver meaningful increases in horsepower and torque while preserving drivability, reliability, and factory-level safeguards. The focus is on usable power, improved throttle response, and optimized torque management—enhancing performance across the entire rev range.
By increasing mid-range torque and refining power delivery, acceleration becomes noticeably stronger and more responsive, particularly when exiting corners and during high-load driving. The vehicle feels sharper and more engaging without sacrificing everyday usability.
DME Tuning software securely stores your original factory ECU data, allowing the vehicle to be returned to stock at any time.
