Has anybody done any testing with this? Other than EFI live, I am looking for the best programmer that gets the best fuel economy... I bought the truck for my wife and she drives alot.. PPE? Quadzilla? Edge? Ive never got a tuner for economy so I dont really know.. lol... Any help would be appreciated.. Thanks!

Do some research on your options, answers like this are usually answered like "I have X tuner and now I'm getting 25 MPG", so know what your getting into. Different driving styles will affect how tuners affect economy. Please fill out your signature so we know about the vehicle in question.

I vote NO to the Edge Evolution.

I'd like to try the Predator. Also heard that the Superchips is pretty good for eccconomy.

I have always had very good luck with PPE tuning for economy. I would recommend looking into them. I have some used units for sale as well as new units. Let me know if I can help.

Why are you not interested in EFILive if you are looking maximum drivability and efficiency? We have very affordable options that are easy to install and offer the best tuning you can find.

I just got a Duramaxtuner DSP5 and so far I love it, I have gained approx 3mpg, and its hard to keep your foot out of it. Nice smooth power, no rattles, alot quieter when the pilot injection turns off.
