Great products backed by great customer service!  
Kansas City, Missouri   

I've been a repeat customer of Double R Diesel for two years now. I've always experienced excellent customer service. All of my orders (tuning and parts) have been filled promptly. Any questions that I've asked answered quickly as well. They offer some great products, and they back them with excellent customer service.

DRD is the best at what they do. I got the complete pkg on time, and during install I had questions, and they contacted me right away and answered my concerns on Christmas weekend no doubt. That's going above and beyond for a customer. The install was great; the tuner is excellent, customer service is excellent, the power this truck has now is unbelievable. The sound tunes are wicked.

Ray was excellent, bought the complete package turner, 5-inch exhaust, air breather, EGR delete, and def delete. Followed Rays instructions. It was the best thing I have ever done for my truck; Truck runs awesome, mileage was an improvement, no issues at all.

Thanks for the help!

Thank You!

Truly the best  
Wasilla, Alaska   

I have purchased a couple different tune packages and have to say that I couldn't imagine going with anyone else. I always get an almost immediate response to emails and questions. I get my tunes within hours, no joke. Needed a retune after a full-blown transmission rebuild on my 68RFE - got it later the same day. Smooth as butter shifts and smooth power delivery through all gears. Awesome sound tunes, too. Love them all! Not enough good things to

Not enough good things to say about these folks - so I'll keep it short and sweet: if you want the highest quality tuning with top notch customer service and expertise, Double R is the only choice.

DRD is the man!! Obviously, everyone can speak to his amazing 1st class service and timely responses. I purchased the complete option and it was without a doubt the best decision I've made with this truck. Tunes are dialed in, shifting is smooth, power is at the wheels in a hurry, and there was zero issues with install and zero changes had to be made to the tune file. I couldn't be more impressed. I run the 12 valve sound

I run the 12 valve sound tune, and, I highly recommend the 12V tune. Exhaust brake and turbo certainly seemed to wake up too! Very grateful, thanks, Ray!
