What Our Customers Are Saying

I had a positive experience at True Horse Power Diesel Performance Shop. They did a great job on my car, even though I don’t own a diesel. Their willingness to assist was much appreciated. When other shops were not able to help due to my car being to low to put on a lift, they were quick to help me. Thank you to Robert and his team.

I'm from MN and experienced issues with my diesel engine on my RV upon arrival in Kerrville, Robert got me right in and his technician jumped right on it to determine I needed to go to the dealer, no time wasted, in and out and they wouldn't charge me a thing even with parts removal and reinstallation to help pinpoint the issue, wow, these Texas boys are awesome, so impressed and thankful, highly recommend this shop.

Rob and Crew are building some awesome trucks. We have enjoyed working with them bringing a number of massive builds to life. Top Notch Customer service with a willingness to go above and beyond to ensure their customers have the build they want. I recommend them highly for your big truck build or diesel performance build. They are a solid shop!
