About
MMG Powerhouse Automotive is owner-operated and built for customers who want more than a basic parts changer. I handle mobile diagnostics, no-starts, electrical problems, brakes, starters and alternators, along with advanced repairs such as timing work, engine and transmission replacements, and performance upgrades.
I specialize in Ford Mustangs and Coyote-powered vehicles, with hands-on experience working on GM, Mopar, European vehicles, trucks and everyday daily drivers. I use professional-grade diagnostic equipment and real testing methods to identify the actual problem before recommending parts—no unnecessary guessing.
Whether it’s a daily driver or a high-performance build, you’ll receive straight answers, clear communication and quality work from someone who takes pride in solving the problems other people struggle to figure out.

I brought my 1993 Mustang Fox-body to MMG Powerhouse after replacing multiple alternators and even changing the dash, but the car still wouldn’t charge. Demarcus didn’t just throw more parts at it—he tested the system, traced the problem to the alternator’s charging/exciter circuit and repaired it correctly. Now the battery light operates like it should and the alternator is charging properly. He also explained what caused the problem and how the circuit works. If you need someone who can actually diagnose electrical issues instead of guessing, I definitely recommend MMG Powerhouse Automotive.
