About ProtoTuned

Led by tuning specialist Elie Seif, ProtoTuned offers a highly customized approach to performance tuning with deep expertise in BMW DME systems. With a background in both engine building and competitive motorsports, Elie brings a rare balance of practical mechanical knowledge and tuning mastery. His personal S54-powered E46 M3 competes in both Time Attack and Hill Climb events, and that hands-on experience translates directly into the tuning strategies he applies to customer builds.

Every tune is approached with precision, transparency, and a deep understanding of how each mechanical component works in harmony. This service is ideal for serious performance builds and enthusiast drivers seeking expert-level calibration.
