    the best & realest !!!!!

    had problems with me X3 stopping out of nowhere with the EML BRAKE 4x4 light & my dealer proved me at 2000 for a part so I did some researching & found rpm & man I’m so thankful I did I was skeptical I would have the same problem when I received the dme but I was proved wrong my X3 drives like brand new with NO CUTOFFS & they sent me a new programmed key for a great price all plus these guys did it all within a week !!! thank you guys so much you’re the best .

    Hello Jose,

    It's feedback like this that keeps us going! Thank you for your kind words and we're so happy that we got your baby back on the road! :)

    Fast service

    fast and frendley service


    So far do good, I put it in the car and it started right up. Thank you

    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.

    Great Service.


    Thank you very much for the service! :-)
    The ECU worked fine and it was real easy to pair with the EWS. I will definitely be telling all my contacts in the car world about you. Thank you again for all the help!
