    I’ve been using Texas Diesel Injection since 2010 when I first took my 2004 Duramax in for Robert to work on. Now Travis and the crew are working on my 2006 Ford Powerstroke 6.0. I’d never have anyone else except TDI work on my trucks! Big shout out to Bryan for always taking care of me! Thanks TDI!!!

    I took my truck to TDI after I had diagnostic done by a previous shop who told me I needed a significant amount of work on my 6.7 powerstroke. After talking to TDI they wanted to pinpoint the issue and not just throw a significant amount of new parts to solve the problem. Their team worked to pinpoint the issue and confirm that the new fuel regulator solved the fuel issue. This is a great shop that truly cares about their customers and work with them to get their truck back on the road. While they had the truck they recommended a few other items such as the DCR conversion, CCV, and cold side pipe upgrade which I ended up doing and very thankful for their recommendations.

    First time deisal owner recently purchased a Ford excursion. I took my truck to them just happened to find them searching for a deisal mechanic close to me. I am 100% satisfied with the amount of work, time and effort it went in to get my excursion right and ready. Brian and Levi were very responsive, respectful most of all did not hold anything back that needed to be addressed. Want to give a big shout out to Dalton who was the tech that worked on my truck. He went above and beyond to get my truck in shape. Highly recommend if your looking for a deisal mechanic TDI is the place for you.
