What Does PPEI’s Tuning Do For My LB7 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 300 hp and 520 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 LB7 Duramax, we measured 250-wheel hp and 450-wheel tq. The baseline shows a powertrain loss of 50 hp and 70 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 LB7 calibrations redefine the limits and safely go beyond the OEM’s performance.
• PPEI’s LB7 calibrations may produce up to an additional 230-wheel horsepower above the OEM baseline. PPEI’s LB7 performance calibration brings the overall horsepower up to just shy of 500-wheel hp and 700 lb-ft of torque. Furthermore, PPEI offers a seamless method to change between 5 different power levels (tunes).
