SERVING PORTLAND

Portland is an easy run across the bay, and it's home to plenty of diesel trucks that tow, haul, and commute daily. We handle everything from a first custom tune to full engine and transmission work.

If you're not sure what your truck needs, start with a diagnostic session. We'll tell you what is healthy, what is coming due, and what can wait.

About the Coastal Bend: The Coastal Bend runs on salt air, boat ramps, and work trucks. Between the marinas, the ship channel, and the haul roads, trucks here tow heavy, idle in traffic, and sit in humidity — a duty cycle that punishes cooling systems, transmissions, and fuel systems alike.

WHAT WE SEE HERE
Full diagnostic sessions
Custom tuning for daily drivers and tow rigs

Portland to Our Shop

We work out of one shop in Rockport, Texas — no mobile units, no subcontracted work. That means the same technicians who diagnose your truck are the ones who tune and repair it.
