I did a lot of research and decided to go with DRD simple because Ray has put out a ton how to videos helping you through the process. I ordered the lite option and the EGR cooler delete kit from them. Everything was delivered that week so I could install that weekend. I was nervous about changing the ECM but I knew it had to be done. The install went smoother then I expected and when I did have a question for Ray I got a response in a few minutes after sending the email. From the engine tune to the transmission tune, everything has worked flawlessly. Thanks to everyone at DRD for making this change to our truck go this easy.

Fresh install  
Merica!   

I installed my new full tune MM3 today. It went in as per the video with no issues. I can't wait to start removing my old exhaust and put in a flow Pro.

Two thumbs up!

If your like me and hate your Ram diesel due then look no further! I tried filing complaints with Chrysler and NHTSA to no avail. Was gonna trade my truck in and the deal fell through. Glad it did because I started researching tuners and every site and comment praised DRD's customer service...so I cam here.

JJ has been amazing at emailing me back and forth as I narrowed down what I wanted, gave a military discount HOOYAH, and the MM3 is a Beast. I got the lite version and love it. Whole new truck. Did full deletes last weekend and 5" TBE. The truck really gets up and goes now. I love it!! Don't hesitate these guys are on point!

My truck was fully deleted using a RaceMe Ultra before I had even made my first payment. I was using the box tunes and ended up burning through my OD clutches which lead to me building my transmission. I was having issues with my TC slipping so I went with a custom tune from Ray to aid in troubleshooting the issue. Ray was helpful in all the ways he possibly could have been to help me through a 2 month

My truck was fully deleted using a RaceMe Ultra before I had even made my first payment. I was using the box tunes and ended up burning through my OD clutches which lead to me building my transmission. I was having issues with my TC slipping so I went with a custom tune from Ray to aid in troubleshooting the issue. Ray was helpful in all the ways he possibly could have been to help me through a 2 month long troubleshooting ordeal. Ended up being the pump but boy was I smitten that I got a tune from Ray. I have been running the latest firmware and tune from Ray for over a week now and have to say that my truck has never shifted or performed better since the day I bought it. The customer service and experience you get from working with DRD is some of the best you can find. I don't normally write reviews and I have no affiliation with DRD but felt compelled to do what ever I can to support such a great group of people. Hats off to the DRD team and I wish you all the best and hope your business thrives for many years to come!
THANKS!!

Customer service second to none!!!  
Tennessee   

When I was looking for a tuner I emailed these guys on a Thursday night and was shocked to get a response within 45 min. of sending the message. I ordered the whole kit a couple days later and every thing was delivered earlier than expected! The tunes really brought this truck to life and increased my fuel mileage by 2-3 mpg when pulling a Heavy trailer.
