Short but sweet
I had a little bit of difficulty with the initial download but the patient, friendly and knowledgeable operators are only a call away during business hours. The guy walked me through the entire process in no time. Installation wasn't too bad but they could use a better piggyback for the fuse. Buy one, you'll see. I erased the engine code caused periodically by my cold air intake, raised the speed limiter and raised my shift rpm's in minutes. I got T-boned that day so performance? Not sure yet.
The Diablosport Predator Tuner did exactly what it claims. IT PERFORMS! This one of my best investments towards my 06 Dodge Ram. It gave a lot more throttle response, better mpg(1 mpg better), and amazing transmission reprogramming. My ONLY complaint is that it took me and a computer friend a couple hours to find the right driver to use the usb-to-serial cable. You have to do this in order to update the device. Other then that its a great product and recommend it to all vehicle owners.
