GMG is North America’s leading Ferrari tuner and an Authorized Tuning partner and conversion center to Novitec Rosso for over 13 years.
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.
Using our Mustang 500SE 2WD and 4WD chassis dynamometer housed in a sound proof cell, our dyno test cell is capable of producing a controlled environment and proper airflow to simulate all road and race conditions. The end result is a properly calibrated tune whether you are running a stock style ECU or a complete independent standalone ECU. GMG’s dyno cell has been used by today’s leading automobile manufacturers and top tuners.
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.

GMG is proud to be a technology partner to Beissbarth and is one of the exclusive facilities in North America to this technology since 2004. Beissbarth is the OEM supplier of alignment measuring equipment to some of the leading automobile manufacturers in the world including Porsche, Audi, Mercedes, BMW, VW and Rolls Royce as well as the chosen aligner for Porsche Motorsport on the 911 GT3R Hybrid.
The Beissbarth alignment machine is one of the most technologically advanced on the market, which is not a surprise considering Beissbarth has been manufacturing this type of equipment for over 100 years. The aligner is so precise and advanced that it is also used as a measuring device for collision repair to pinpoint problem areas. It even has the ability to compensate for lowered vehicles and vehicles with suspension geometry out of factory specifications.
Whether your car is stock and in need of alignment or your car has been lowered and you need to ensure it is aligned properly to minimize tire wear, GMG technicians will get the suspension geometry into perfect specifications, be it factory or custom, without any problems.
The level of equipment and training that each of our technicians receive has made GMG the facility that many dealers and other shops in Southern California subcontract their alignment work to. GMG is the shop of choice when others can’t get a car into specification or if they have a car that is modified beyond the scope of a standard alignment machine.
For those customers who require more track-oriented alignments, GMG offers specialized care and expertise including setting rake, adjusting ride height, corner balancing and more.
