MM3 Tuner and Double R Diesel

**USMC77** · 02-09-2020

Just wanted to give a shout out to the guys at Double R Diesel as many others have. I recently purchased the MM3 tuner and purchased the WARP Tunes from Double R Diesel before I went on a 4500 mile trip across the country. Had issues immediately due to a version mismatch which I found was due to an old tune on my truck. I worked with Ray and MM3 to get a stock file put back on my truck and get it tuned with the Warp tunes in just a few hours all before making that long trip. Right away as soon as I touched the pedal i felt a difference, this thing wants to go. Shifting was better, everything felt way more responsive and that was on the lowest tune. I drove through the Rockies, stayed overnight in -8 degree weather in Breckenridge and the truck performed with no issues. The truck was purchased used and was fully deleted already with a custom tune on it but the shifting was horrible, it would stumble and I felt lots of rough shifting especially while towing my fifth wheel. The difference is night and day, I typically don't even write reviews but I couldn't be happier with how everything turned out.
