      Real performance gains!!!

      I felt dumb after the purchase because I was thinking there is no way a remote tune can make such a difference. This tune made the biggest difference. The 2008 328i spins them in second no problem now and I still have to install the catless headers!!! If your looking for big performance gains this is the way to go. These cars are so detuned from factory so this tune brings it to life.

      Hello Daniel,

      It's a breath of fresh air reading your feedback! You're on point that it does make the biggest difference! 'Spins them in second no problem now' We love it! Stay safe and keep us in the loop once you install the headers! We're looking forward to hearing from you again soon!

      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 :)
