After all of the reading and comparing programmers and tuners, I had very high expectations for the DRD Lite tunes on the MM3 Programmer. I am very pleased to say that the expectations were met.

Hardware and software installation was a breeze. Even the EGT probe was easy to install with a 3/8" battery powered drill and tap. I removed nothing except the tubes from the filter box to the turbo. Customer support was fast, thorough, patient, and always polite. A great experience and excellent products.

Prior to installation, my 2012 crewcab, regular box 4x4 averaged 17.2MPG. After installation (3 tanks of fuel) I have run the 120hp tune and the pickup is averaging 18.4MPG. the great news is, that mileage includes the couple of times per tank I just have to do some serious accelerating because it is now fun. I keep track of each fill up in a spreadsheet on the phone as I fill up.

Thank you Ray and the DRD crew!
