    Who is the tuner/calibrator

    PPEI, also known as Power Performance Enterprises, Inc., is led by the business owner and lead calibrator/tuner Kory Willis. PPEI began calibrating/tuning back in 2008, specializing in Diesel Performance but has since expanded into the Gas and Powersports industries. Kory and the team at PPEI have set many world records along with continuing many industry “firsts.” We take pride in knowing that Kory not only prides his work but also thoroughly enjoys setting expectations high for our team so our customers can have the best products and service in the world.

    What does PPEI’s tuning do for my LMM Duramax

    • Tuning is intended to increase the horsepower (hp) and torque (tq) the engine can produce. OEM manufacturers, like GM, show vehicle hp and tq based on the amount of power produced by the engine, at the engine, which is 365 hp and 660 lb-ft of torque. 
    • PPEI, unlike the OEM, measures hp and tq at the wheel. What does that mean? – It means PPEI measures power that the vehicle produces to the ground showing the amount of powertrain loss from the engine, through the transmission, to the wheels. PPEI refers to this as the “baseline,” in this case, for the LMM Duramax, we measured 320-wheel hp and 620-wheel tq. The baseline shows a powertrain loss of 45 hp and 40 lb-ft of tq. 
    • PPEI’s primary focus when tuning or creating a calibration is focusing on the overall efficiency. Many individuals search for the most horsepower & torque and view it as the “best tuning,” however, more times than not, it’s quite the opposite. Many tuners advertise tuning based on the highest hp & tq, surpassing the threshold of efficiency. When the threshold of efficiency is overpowered, issues start showing up, which can be as minor as poor fuel economy or as significant as transmission and engine failure.
    • At PPEI, we love our performance, but we develop all calibrations around reliability, giving you peace of mind no matter the situation. Whether you’re at the dragstrip or hauling a heavy trailer across the nation, PPEI’s LMM calibrations redefine the limits and safely go beyond the OEM’s performance. 
    • PPEI’s LMM calibrations may produce up to an additional 200-wheel horsepower above the OEM baseline. PPEI’s LMM performance calibration brings the overall horsepower up to 520-wheel hp and 920 lb-ft of torque. Furthermore, PPEI offers a seamless method to change between 5 different power levels (tunes).

     

    The PPEI stock trans engine calibrations are designed specifically for trucks that are utilizing a stock transmission to ensure the user can't push the vehicle beyond limitations of the stock transmission. These calibrations are engineered to provide you the most efficient power and performance without exceeding the threshold of efficiency while maintaining reliability. PPEI has thoroughly tested and refined each power level to give you the best tuning in the world for your Duramax. The PPEI built trans engine calibrations follow the same idea with the exception that the built trans engine calibrations are designed only for trucks with upgraded or modified transmissions allowing the truck to support more power safely. 


    Power Level 1: Economy +30/30 RWHP

    This power level is designed to reduce lag and improve throttle response for optimal efficiency. 


    Power Level 2: Heavy Tow +60/60 RWHP

    This power level is designed for towing anything over 15,000 lbs. Do not use any power level higher than power level 2 for towing loads that exceed 15k lbs as this will surpass the stock engine and stock transmissions threshold of efficiency which increases the chance of mechanical failure and decreases overall reliability of your vehicle.


     Power Level 3: All Purpose +100/120 RWHP

    This power level is designed for towing anything under 15,000 lbs or daily driving. This power level is what we at PPEI recommend for everyday use as it boost overall all performance while retaining  reliability. 


     Power Level 4: Street +120/160 RWHP

    This power level is designed for daily driving but has a little spice to make things interesting while keeping your Duramax safe and reliable without pushing the factory components beyond their abilities. The street calibration packs a punch that it doesn't come with from the factory. This calibration is not intended to be used for towing as it could surpass the threshold of efficiency.


      Power Level 5: Performance +150/200 RWHP

    This power levels development process specifically derived for the purpose of giving you a wow sensation when you press the peddle. Obviously, the wow-factor doesn’t exist from the factory as the LMM is kind of boring and rightfully so. At PPEI, we thoroughly enjoy pushing vehicles to their limits and finding the weak link, which is why the aftermarket industry for hard parts exists. Without knowing the weak link, the automotive performance industry would be throwing darts blindfolded. This calibration is specifically designed to be used a ¼ mile at a time. PPEI highly recommends that you do not tow at all or daily drive in this calibration as it pushes the limits surpassing the efficiency threshold of the factory components.
