- GAGiancarlo AngeliniAug 13, 20265.0Wow, my injectors were shot as well as other issues. 1 week later, all fixed, runs better than ever! Matthew and his team are amazing! Wasn't cheap, but you get what you pay for!! Gave me a tour of the shop. Thought I was at NASA! Tremendous investment in state of the art equipment!! Very thankful for what they can do, very conscientious, they want you happy!!! I am very happy!!! Thank you so much!!!
- RWRodney WeeseJun 13, 20245.0Was referred to them as an installer for Banks Power. Had a Banks Monster Ram and Banks Intercooler installed. Drove over to discuss the job with Mathew. First impression was he was very polite, willing to answer any questions and willing to talk and treat me as a person. Gave me a bit of a tour of the shop. One thing that surprised me was where the cars are worked on. For a mechanics shop it was real clean. To me that says everyone takes pride in the place. Diesel Systems is a bit of speciality facility so they probably won't do some of the basic things. But after touring and knowing they are installer for Banks and seeing them working heavily on the fuel systems and being tied into Bosch I felt better about them doing my job. Do to a previous jjob they had and a parts issue it took a little longer then I wanted but I am confident the job was done right and done by people who care.
- TWTyler WrightJun 8, 20222.0I had a completely bulletproof done, head gasket job done thermostats about $6500 dollars worth of work done. It’s been less than 30,000’miles and my head gaskets are leaking again. But since it’s been 3 years they don’t care.
