      Fantastic work

      I’m beyond impressed with how great the tune turned out. The only thing I’m more impressed with is the customer service. They were with me every step of the way. Even went so far as to give me an e85 tune that they do not advertise.

      Hello Justin,

      It was awesome working with you! Happy customers such as yourself is what keeps us going! Thank you for the awesome review!

      RPM MOTORSPORT has been excellent in finding the right tune for my drive style while staying within safe boundaries for my car. They are super helpful in even just discussing in depth which tune or products suits your needs best. I’d HIGHLY recommend them to anyone looking for a tune that comes made with love and backed by over 10 years of experience! I will be using them to tune all of my vehicles.

      Hello Noah,

      We're stoked to hear about the results of your latest tune! Discussing in depth is key in achieving the best results, thank you for giving us this awesome feedback! We're looking forward to tuning the rest of your fleet. Enjoy and stay safe :)

      Great service!

      I am a novice when it comes to ecu tuning and tuning in general, so I was a little timid about going into this step of getting my car done. However, Zach and everyone at RPM were helpful and easy to work with. My 2013 Mini Cooper with a new rpm stage 2 tune, is an absolute blast to drive and is rock solid. I will definitely come back to them again with my next project.

      Hello Matt,

      We totally hear you regarding the whole tuning world. It's a jungle out there :) We are so happy that you're enjoying the power gains and overall drive of the car. Stay safe, and keep us in the loop! Have fun! :)
