      Quick, easy, and fantastic results

      Needed a new DME for my daughter's X3. Called customer support where they promptly answered all my questions and then some (definitely above and beyond). Placed my order, sat back and wait. DME arrived in great condition. Installed, cleared codes and voila! X3 running like she is new again. Hopefully I won't need another one, but if I do, RPM will be my first and only stop.

      Thanks for getting my daughter back on the road at more than half the cost of what the dealer would've charged me. Both she and I are greatly appreciative of the service that you provide.
