Maryland Performance Diesel

Absolutely horrible. Horrible customer service. Mechanics are completely incompetent. Terrible in every expect. Never do business with them. Truck has been sent back OVER THEEE TIMES. each time the trains has leaked. Trans was not put in properly. If I could go back I 100% would never work with them. Ever.

These guys our awesome, went in yo get the edge insight cts on my first diesel. They hooked me up big time being military. If your in the dc, Baltimore area and you need anything for your diesel no matter if it’s a ford dodge or duramax this is the place to go! Thanks to buddy for all the help and letting me pick your brain a little since this is my first diesel n had a lot of questions. Hands Dow the best diesel shop around!

After getting horrible customer service and a repair that failed after 3 days I was referred to Maryland Performance Diesel (MPD). I was still upset about the quality of work the previous shop had done so I was skeptical. Good Diesel mechanics are hard to find and it seems there are more opinions in the industry than actual people that know what their doing. This isn’t the case with MPD. When I arrive I told my story to Buddy at the counter and he said they could help. Craig the owner took interest and came outside to put his eyes on my issue. He made a repair recommendation and offered advice on a few additional upgrades that would make my truck run better and longer. I asked him if I needed to get the parts or he was going to and he said «we make them here.» Not only is MPD excellent at repairing and enhancing diesel engines but they have a machine shop in house and a full line of aftermarket parts. Last week I picked up the latest copy of a national magazine that focuses on diesel performance and I was shocked when I saw MPD with a full page add for the parts they make. I had no idea how serious of an operation these guys run. I thought I was going to another mechanic shop not a national parts manufacture. I can’t say enough about how good MPD is. I have zero complaints about any of the work they’ve done for me. The original repair they did has never been an issue and Craig was right, the truck runs better than it ever has. I’m a MPD customer for life and I recommend using them too if you want it done once and you want it done right. Great job guys.
