Every once in a while we come across electronic programmers that are supposed to deliver a whole new truck to your driveway. We are skeptical, as we feel most of the public is. How can this few-hundred-dollar unit do what the manufacturers cannot seem to master? Better fuel economy and more power with no sacrifices? We decided to test the new Hypertech Max Energy Programmer on an '08 Ford F-250 Super Duty to see what kind of results we could get.
- Three horsepower settings
- The first two settings are the same as the Hypertech E-Con tuner for improved fuel economy
- You can raise the top-speed limiter
- You can raise the rpm rev limiter
- Adjust shift points and firmness
- Recalibrate speedometer for different tire sizes
- Recalibrate for gear-ratio change
- Lower cooling-fan on/off temps
- Read, display, and clear DTCs (check-engine light)
- Updatable over the Internet (via supplied USB cable)
- 50-state emissions legal
- Easy plug-and-play installation (takes anywhere from 3 to 15 minutes)
With all those claims, it would almost seem foolish to not give this unit a try. Once we opened it up, we plugged it into the truck's OBD-II port, and it automatically began to run its programming. It starts out by asking you to turn your key to the "on" position without cranking the motor. Then it checks the computer for any DTCs (diagnostic trouble codes) and gives you the option to have them cleared or to leave them alone. After that, you can break into the various options as listed. The unit can only be used on one vehicle at a time, and no matter what tuning you adjust, you can return everything back to stock. That is a nice touch in case you do not favor the results.
So what did we think? After a few weeks of testing, we have noticed a 2-mpg improvement in fuel economy, which has been great on our big gas-guzzling truck. During the Stage 3 setting, we noticed a significant power increase but have not had the chance to strap it onto a dyno yet to provide actual numbers. We were able to recalibrate our speedometer, which was nice, considering we are running much larger 37-inch tires. We were also able to raise our rev limiter, which has been great in the dirt and when towing. Our new Hypertech unit has been a pleasure, and we suggest you give one a shot sometime. Doing the math, the gas savings alone will pay for the unit in no time.
