About
East Texas diesel, built by people who drive it.
Longview Diesel Performance started in a two-bay shop with a single goal: do the job the way we'd want it done on our own trucks. A decade later we still run that bar. Honest diagnostics. Real parts. Tunes proven on the dyno, not a forum.
We work on Duramax, Powerstroke, and Cummins — from daily-drivers and tow rigs to fleet trucks that have to be on the road at 5 AM tomorrow.

How we run the shop.
Principle
Diagnose first
We never throw parts at a problem. Full scan, tear-down, and a written report before any work is authorized.
Principle
Quote it straight
What's the part. What's the labor. What's the why. No 'shop fees' that nobody can explain.
Principle
Stand behind it
12-month / 12k mile warranty on most work. Builds get their own coverage spelled out in writing.
