    Excellent Service

    I had numerous codes associated with a bad DME, and my car would stall shortly after starting. I ordered the service on Saturday, they sent me an overnight UPS label Monday morning, I mailed it out the same day. UPS didn't deliver it until Wednesday... they fixed it same day, mailed it out and it was in my car Thursday. It has been running perfectly ever since. Can't ask for much more than that! (Maybe go with Fedex, haha)

    Hello Rick,

    We're so happy that you got your baby back on the road! Thank you for taking the time out to write this awesome review!

    Fast & Thorough Service on 2004 BMX X3

    RPM turned around my order very quickly. I had the P16A0 code on my 2004 BMW X3, their reprogramming fixed the issue and the car runs great now. Would highly recommend RPM Motorsport for all DME repair and replacement needs, they are true experts.

    Hello Robert,

    It was a pleasure serving you! Thank you for your awesome feedback and we're looking forward to hearing from you again soon! :)
