Tuning 2014 BMW 328D

I had a countdown timer for an SCR/Adblue system fault. I purchased the delete tune and the guys at RPM got me fixed up. I ordered delete parts and the tune was quick and easy to install. I’m running the xtreme performance tune and the car has come alive. A lot more power that’ll throw you back in the seat. Very thankful for the wonderful support from RPM. They say it could take up to 2 days to get your tunes back but I got mine 5hrs after sending my stock file in. Excellent service and excellent company!

It was a pleasure working with you Cole! Thank you very much for all the kind words, I'm glad to hear you're happy with the tune!


As always a perfect job. The engine control unit was plug and play!

Thanks for the review Chris! Always a pleasure working with you guys.

Mini Cooper CAS module

After a quick round trip of the module to RPM, I re-installed the module and all seems back to normal. Thanks for the module service.

Very impressed with the services.

Very helpful and knowledgeable on the product and quick turn around on repairs. I will be using their services again on the next one. And the repaired unit worked just like a brand new one.

Glad to hear you had a positive experience Billy! Thanks so much for the feedback :)

Highly recommend RPM!

Works exactly as described and helped make my 535d run much better. Arrived super quick and easy to follow instructions. Great communication and any questions I had were answered same day. Highly recommend and will be using again in the future. Special thanks to Lee for following up and checking in frequently on my progress/ status.

MIni Cooper CAS3 Heat Repair Service

Awesome job done, turn around time was fast. Installed repaired unit and car started right up and is running like a champ.

Thank you Lee...RPM Motorsport rocks!!!

Thank you for taking the time to write this review Dirck! Glad you are happy with the service :)

Awesome Service

Hands down, besides Napa…this is honestly the best customer service I’ve ever had. For once it feels amazing to get quality work without someone trying rip you a new a-xxxx. The euro shops around tried to rip me off, then I found this RPM Site. At first I was skeptical and I thought the reviews were fake, but they’re real. The turn around time is indeed fast, “Jimmy Johns” fast! Mr. Lee and his team is the best, I thought my first dme was the problem because my mini stayed at a high idle after start up, Mr. Lee sent out a replacement within two days, then later I found out that the gas pedal was the problem, replaced that, now im on the road again! Again thanks Mr. Lee.

Saved the day!

After my x5 sat at the dealer for 31/2 months I decided to try myself. I found RPM on line , sent them my CAS unit and keys, received the unit back 3days later , gave it to dealer to install, next day I drove it home! Great service thanks!!

Thanks for the awesome review Scott!

Mini Countryman S DME repair

As promised, RPM repaired the DME module on time as quoted. The car was bricked, and Mini USA isn't even taking wait-list names for OEM modules. RPM saved the day! The car is running perfectly again. Very impressive service and a quick turnaround.

Thanks for the kind words Tim!

The technicians at RPM were very efficient and professional through the whole process as usual. Provided a second key and cloned a 2nd hand DME and it all works flawlessly. We will continue to use their services in the future!

Thanks for the great review Jesse! Looking forward to working with you again soon!

Great job by RPM

I had the opportunity work with Lee at RPM. He was wonderful to work with and he did everything he said he was going to do. The next day shipping was simple and easy. The car is working great with the reprogrammed computer. Thank You so much!!!

Thanks for taking the time to write this awesome review Pat!


Problem Solved

I was hesitant to send my CAS and Key to Canada. After 3 months of trying to get a new replacement CAS through different sources I concluded it was my only choice. Turn around time was as advertised and the repaired part was plug and play.

Thanks for the review Kerry! It was a pleasure helping you out with this one!

Mini R56 CAS Repair

RPM did an excellent job repairing the CAS on my Mini Cooper!
The extra key works good also, I just lost the proximity access.
Turn around on shipping was fast!

Exceptional service, products and staff

The five star rating is a great indicator of their service however, doesn’t go far enough to demonstrate the quality of the product offering and speed with which RPM delivers. My M5 was essentially dead as one of the DME pins had become loose and sporadically placing the car into low power mode. BMW Germany was unable to provide a replacement DME due to chip shortages and would not provide an ETA to the dealers. I reached out to BMW dealerships in the USA only to learn they too were unable to obtain a new DME. In fact they confirmed the entire USA BMW
dealership network had none and were backordered.

After much research I found RPM but they were small and despite the numerous five star reviews I was still a tad unsure. Well I called and spoke with Lee who was very well versed on the BMW DME and helpful in matching my needs with their product offerings. Needless to say I placed my order and prior to the end of the week my remanufactured DME was installed into my M5. It was truly a plug and play experience as my car started immediately and runs exceptionally well.

They are exceptional people with fantastic products!! I have no hesitation in recommending RPM for any of your needs which they can fulfill.
