General Motors (GM) Tuning

MoFab is the leader in GM tuning with years of experience on all LS models. From a 1200hp ProCharger Corvette to a 600hp LS swapped Land Rover Defender to a supercharged Camaro, you will almost always find a GM motor on our dyno. Have a hotrod with a LS motor? We tune those too!

We have a history tuning older carbureted GM vehicles that have been converted to an electronic fuel injection (EFI) system using Holley EFI or Fast XFI.

With our partnership with HP Tuners we can tune other GM products including Buick, Cadillac, Chevrolet, GMC, Oldsmobile, Pontiac and Hummer! We can also tune for GM’s large vehicles including Tahoe, Suburban, and Avalanche.
