GMG specializes in the performance tuning of Porsche automobiles. GMG is an authorized dealer and technological partner with many of the industry leading companies and we also engineer, develop and manufacture our own line of performance products and wheels under the GMG World Challenge and LMS lines. With the technology, experience, and knowledge transferred from our professional race program, these upgrades will further refine will further refine your road going vehicle.
GMG is a leading installer and tuner of standalone engine management systems from Motec, Link, and AIM. As a development partner with GIAC, we can go beyond the ECU reflashing offered by most shops and, instead, perform a custom calibrated software tune for your specific vehicle with your specific hardware.
GMG offers a concierge service based around a driver’s particular needs for each tuning project. Our staff is trained and well-versed in the needs of a particular driver and his or her intended use of the vehicle. Unlike most shops that sell parts out of a catalogue, GMG brand specialists have firsthand experience with the products, services and results involved around each vehicle modification. No two individuals are alike so no two vehicles are tuned the same way at GMG.
