DRD Tuned  
Wyoming   

DRD Lite Tuning package with DRP EGR Delete Kit, and EGT Sensor, 5" Jamo Exhaust, Shibby Engineering plug kit, FTE 30" resonator.

This truck runs and shifts fantastic now. It was horrible before and drank tons of DEF fluid. Easy install with clear directions and very informative how-to's on the DRD YouTube channel.

Outstanding Tuners and Support  
Naples, FL.   

DRD is hand down the best in the industry in tunes and support. I was a chief pilot/mechanic for a heavy equipment dealer in the mid-west and aircraft maintenance shops and no one is more on the ball than DRD with support. I emailed at 11:30 PM and DRD answered me back in a few mins and told me how to take care of the problem, that I found out I had induced. I had 15,000 miles when I installed

DRD is hand down the best in the industry in tunes and support. I was a chief pilot/mechanic for a heavy equipment dealer in the mid-west and aircraft maintenance shops and no one is more on the ball than DRD with support. I emailed at 11:30 PM and DRD answered me back in a few mins and told me how to take care of the problem, that I found out I had induced. I had 15,000 miles when I installed a DRD EGRLESS tune and the last 500 miles the truck is better than when I bought it new.

Thanks, DRD. You are the best!

This is how all businesses should be!

I ordered my MM3 tuner and couldn't be happier! Had a few questions before I bought the tuner and DRD was very helpful and quick with their responses. Even after the purchase, DRD still responds quickly to any issues or questions one may have. This is how all businesses should treat their customers. Tunes aren't the only quality service they offer; the people at DRD are even better! I highly recommend DRD!

Top notch tuner and tunes!!!  
West Virginia   

Great tunes and top notch customer service. Hands down the best tuning. Truck runs amazing! Fuel mileage is better also much better.

Hands down the best there is!!  
Bradford, OH   

I've had your tunes going on 200,000 miles now and not 1 issue. Very clean tunes and excellent fuel mileage out of them. I can't say enough about customer service, I've had a few questions along the way, and they always get back with me in a reasonable time. Wish I could give more stars but anyway. Thanks, DRD!!!!
