High-Performance Diesel & Automotive
San Antonio's premier shop for diesel diagnostics, engine builds, turbo systems, ECU tuning, and custom fabrication.
What We Do
Full-service performance shop — diagnostics to fabrication
Diesel Diagnostics
Advanced CAN bus and electrical diagnostics for gas and diesel engines. Root cause analysis, not guesswork.
Engine Builds
Custom high-performance builds from mild street to full competition. We built a 6.6 Duramax from the ground up.
Custom Fabrication
TIG welding, custom exhaust, roll cages, turbo manifolds — if it can be welded, we build it.
CAD & 3D Scanning
Reverse engineering, precision modeling, and 3D printing for custom parts and product development.
ECU Tuning
HP Tuners and EFI Live custom calibrations. Fuel maps, boost curves, and drivability dialed in.
3D Printing
Rapid prototyping and production parts. From concept to physical component in hours.
Built in San Antonio
Where trucks meet precision engineering
Why 915 Industries
Root Cause First
Diagnose before replacing. We find the actual problem, not just the symptom.
Full In-House
Diagnostics, machining, fabrication, tuning, 3D scanning — all under one roof.
Performance Proven
From daily drivers to competition rigs. We build power you can trust.
Tech Forward
CAD modeling, 3D scanning, AI-assisted workflows. Modern tools, old-school work ethic.
