What Our Clients Say
Took my L5P in for some performance work and Zac was very professional and had amazing communication the entire time! Very quick turn around time along with quality work. If you’re anywhere in the Houston and surrounding areas , SJ diesel performance is the place to go!
Zachary is the most honest and straightforward mechanic I have ever dealt with. My truck was giving me a 150 miles toward limp mode warning and I needed someone QUICK. Nobody could get me in for at least a week. Zach answered my call way after working hours and came by the next day to run a diagnostic in my driveway. 2 days later I was up and running. Extremely happy with the work he did and will be using him for ALL work on my truck in the future. Highly recommend to anyone needing diesel mechanic work
"San jacinto Diesel performance" It is one of the places where you can bring your vehicle so it can be repaired in the fastest and most reliable way and at the best price.
Zachary is a very honest person and works quickly to put you back on the road👏👌
Should have been my first choice! Dealership had wiped my original tune from my ecm and I needed another one. Only put it off for another guy because of what was supposed to be convenience. Guy took 3 days of my time for nothing. Got my truck over to Zach and was in and out in less than an hour. Love my new tune. More horses, better fuel mileage, and just an overall better tune! I’ll be coming back for more work in the future! Me and My F350 thank you!
Our Story
San Jacinto Diesel Performance was built on a simple idea: diesel repair doesn't have to be a frustrating experience. Brothers Zachary and Tyler spent years watching the industry's worst habits — rushed diagnostics, inflated bills, and trucks passed between technicians who barely knew them — drive customers away and leave them feeling taken advantage of. They knew there was a better way, and set out to build the shop they'd want to bring their own truck to.
That's why San Jacinto Diesel Performance isn't a corporate chain. It's owned and run by two brothers who are personally invested in every truck that comes through the door. With only two technicians — owner Zachary and his brother Tyler — touching every vehicle, you get hands-on, personal attention every time. No handing your truck off to a rotating cast of strangers, and no compromise on quality.
Both ASE certified with degrees in applied diesel science and over a decade of hands-on experience, Zachary and Tyler bring real expertise to every job. When you bring your truck to San Jacinto Diesel Performance, you're not just another number — you're working directly with the ones who built this business.
