Mercedes Benz Sprinter 2.1L 4CYL OM651 Turbo Diesel 2014 to 2018 Rpm Motorsport Tune

Downloaded PCM software from vehicle and had the Delete and Daily Driver plus installed in software. Getting ready to install in vehicle as soon as my work is done . RPM has been awesome and very good about staying in touch and helpful with any questions. Lee has been a gem helping me make sure that I am on course with this project. Absolutely impressed by the customer service !! Thanks guys , Doug

As soon as I started having trouble with emissions controls I knew it was time to call. This small investment improved the reliability 10 fold. I went with the upgrade and it paid off. I no longer have to worry when the problems are going to start and how expensive they will continue to grow. I’m mechanical and did my own install and and sensor disconnect. Almost anyone could handle this project. Thank you!

Have had zero problems and the car is now running beautifully after the work you guys did.

Excellent customer service always keeping you in the loop with what’s going on.
Turnaround time also was on point.
No doubt these guys deserve 5 ⭐️’s

Great instructions. Worked great. I liked that someone called to follow up and check if there were any issues.

They are prompt and very easy to work with

Great people to work with. Always very helpful and wonderful service. Very quick turn around and never any problems. Thank you RPM for everything you do.. Kenny

I can't say enough about the service from RPM. I diagnosed my car and a team from RPM helped me confirm the issue. I sent the DME over to them and asked hey sent it back very much the next day after they got it. Put it back in the car and the car started right up.
Thank you RPM.

Great job they have done a couple ecu for me

Not only did they advertise a two day turnaround they did a two day turnaround. I have not had a company, especially out of country, have a product ship to them and then receive it 5 days later, until Rpm Motorsport. As soon as I got the ECM back, plugged it in and vehicle fired right up. Not only was I happy but so was my customer. Thank you RPM Motorsport

Great customer service and the product worked

Lee help me all the way I’m very happy I will buy again from them

Mercedes Benz SCR / DPF / EGR Delete (EDC16CP31) Years 2003 to 2012

I sent them my lightly water damaged dme that was still readable as well as a used working replacement dme with matching part number. They cloned everything over including my tune and it’s working perfectly. Very fast turnaround!

Thanks for a great job. As a fellow Canadian living in the USA . It will get better in three years : )

This solved many problems with the car, but the car is a basket case with many more things to be done. It was a barn find not running since 2017. I thank you for your great work on the DME.

These guys are great. Very helpful and got the job done!

I had a no crank/start issue with my BMW which ended up being a shorted out TCU. The shop it was at had already charged me an arm and a leg for the diagnostics and for replacing the transmission position switch. If I would've had them replace the TCU as well, the total cost of the repairs would've been more than the value of my BMW. Thankfully, I found RPM Motorsport. I ordered a programmed TCU for my BMW from them that arrived day after next. I installed it in a matter of minutes, that the shop would've charged thousands for, and she fired right up. I definitely will recommend you guys and do business with y'all in the future if need be.

Product is awesome! was nice and easy to install, worked so far no issues and no check engine lights. Costummer support was very good always in contact that gives you a good peace of mind. Thank you Lee!

As someone who’s hands-on with vehicles, I’m picky about tuning. RPM Motorsports delivered a clean, well-calibrated tune with noticeable gains and no drivability issues. Everything feels intentional and safe. Solid work.

Fast turn around and very professional
Great communication and updates

They did a fantastic job
