GMC Sierra 2008, Max Energy Programmer by Hypertech®. The Max Energy Programmer is one of the most full-function tuners on the market - providing high levels of power and economy for gasoline and diesel engines, with specific tuning applications geared for regular unleaded gasoline and E-85 Flex Fuel vehicles. Other innovative functions allow manual control of cooling fan kick-on temperature, V8 engine 4-cylinder cutoff, tire size calibration, factory rev limiter, transmission shift points, and top vehicle speed. You’ll also be able to read and clear diagnostic trouble codes.

The Max Energy series of gasoline and diesel engine tuners from Hypertech® gives you the ability to increase power, mileage, and towing ability along with other great features the competitors don’t offer. But first, Max Energy series come loaded to optimize timing and fuel curves at all rpm levels, across all throttle openings for your specific vehicle. What does this mean? Economy is increased at part throttle and steady cruising applications, and usable horsepower and torque are increased when the throttle is used more aggressively, or when towing mode is selected. Controlling electronic automatic transmission functions keeps the torque converter from unlocking and gears from downshifting when you need steadier drivability for towing. Additionally, you can expect to see fuel economy gains of 2 to 6 miles per gallon depending on driving conditions. All Max Energy units come with a USB cable and CD for initial activation using your computer. Should new software tunes for your specific vehicle be introduced in the future, they can easily be downloaded from Hypertech’s internet site.
If you have a V8 engine with a cylinder cutoff mode to run on 4 cylinders, the Max Energy Gasoline Power Programmer allows you to vary the parameters of when that occurs, or turn the cutoff function off altogether. For vehicles originally designed to run on lower octane regular gasoline, a performance enhancing algorithm is created for running on regular octane. And if you wish to use super unleaded in your lower-octane rated vehicle, a second power level is created to adapt fuel and timing to make the most out of it – something your vehicle won’t do on its own. A speedometer calibrator function allows correction of speedometer readings when non-stock tires or gear ratios are installed. If that’s not enough, the Max Energy programmer also reads and clears diagnostic trouble codes so you can turn check engine lights off. All Hypertech products are backed with a limited lifetime warranty against manufacturing defects.
Since its founding in 1985 in Tennessee, Hypertech® has been an industry leader in engine power enhancement through the use of software enhancements. In 1986, Hypertech created the original "power chip" which physically replaced factory stock engine control computers and increased horsepower and torque through remapping of computer-controlled fuel injection and ignition timing. As computer controls spread to other vehicle systems such as transmissions, throttle bodies, and variable-valve timing over the years, Hypertech was instrumental in software development that maximized the benefits of each of those systems to push the envelope of performance and fuel economy. In 1994, Hypertech was instrumental in creating the Power Programmer application which made it possible to download software enhancements into an existing ECU, which eliminated the need for replacement chips. Hypertech continues to lead the way today, and CARiD is proud to sell their range of innovative tuners that offer features competitors haven’t even thought of yet.
