About OG-TECH
OG-TECH LLC is a San Antonio–based automotive technology company specializing in diagnostics, performance tuning, custom builds, and fleet services. We bring serious tech to every job — from daily drivers to full race builds.
Built in San Antonio
OG-TECH started with a simple idea: bring real precision to automotive technology in San Antonio. Thorough diagnostics, clean tuning, and a shop that actually communicates with its clients.
Over a decade of hands-on experience across naturally aspirated builds, forced induction setups, fleet management, and electrical work — we've developed a process that's thorough, transparent, and results-driven.
Today OG-TECH LLC serves individual enthusiasts, daily drivers, and commercial fleets across San Antonio and South Texas.
Our Values
Every diagnosis, tune, and build is approached with data-driven precision — not guesswork.
We keep you informed every step. No surprise charges, no shortcuts, no BS.
Modern diagnostic tools, software, and techniques keep us ahead of the curve.
We stand behind everything we do. If it leaves our shop, it leaves right.
