Our Chevrolet 6.6LMM Duramax ECU Remapping also improves drive-ability and economy. The process requires the vehicle to be at our workshop for just the day. Our specialist tuners set the vehicle up on our All Wheel Dyno for a baseline dyno run. We then through our iterative tuning process, tune and revise the tune until it perfectly suits your car and its modifications. All this is done to a safe industry standard ensuring maximum reliability and longevity.
