Diesel Brands and Truck Service Repair

Luke Wilshire

Brought my truck in for an estimate. Their prices compared very favorably to pricing through the internet. Made an appointment for installation of MiniMaxx street tuner, cold air intake and exhaust system. Also had them install power running boards, that I provided. Though installation took longer than I had hoped, it was worth the extra wait. My diesel runs like a bat out of hell. I am most satisfied with Chris and his staff. This is the place to go in San Antonio for a professional installations and all things diesel.

They answered my questions on which smarty was right for my 2006 Dodge Cummins 5.9L. They explained what the best catcher number was for the truck. All together they were just very helpful.

By far the best off road/ diesel shop in South Texas, or the South for that matter. Awesome customer service every time i’ve been in and an always friendly staff. I refer many people to TSD and put my reputation on them. They dont just try and sell you a bunch of stuff they actually help you while you are there and their work is second to none. They’ve had my business since day one and they always will. Highly reccomend TSD and their work.

Shawn Garcia

TSD is exactly what I expect when I think of a performance/repair shop. They are courteous, knowledgeable, great prices, and perform excellent work. I have put the truck to work driving it back and forth from San Diego to TX, racing, and towing without a hiccup. That’s how good TSD’s repair work and tuning is. I have a truck that’s just shy of 600hp that can do anything I want it to do. Thanks to the whole TSD crew. Keep up the good work. This is the husband.

Joyce Stewart
