Freightliner Cascadia 2017 engine DD15, speed was limited to 55mph Arturo and Roger worked on my truck and fixed the issue in a couple of hours. They did system update, replaced nox sensors. Update on review after one month. So I have the same codes and same dpf issue

Great place to go. Guys there are very helpful and knowledgeable. They don't try to run you around with a bunch of bs. Just straight to the point. Brought my own P/S pump, and they put it on for 200 bucks. Great deal that same job would be double or more any where else. They also offer tunes that are affordable and keep the truck the legal. Good guys, for sure. Highly recommend
