Got a brand-new 2014 GM truck with the 5.3-liter engine? Hypertech has a Max Energy Power Programmer for you! PN 32501 offers optimized engine tuning for regular- and premium-octane fuel. Tests have shown a gain of 13 HP and 15 lb-ft of torque using premium-octane gas, while regular-octane gives a boost of 11 HP and 9 lb-ft of torque.

With the Max Energy Power Programmer, you can correct your speedometer/odometer for non-stock tire sizes (from 24 inches to 54 inches) and rear gear ratios from 2.56:1 to 5.13:1. You can also adjust your automatic transmission shift points up or down 500 RPM in 100-RPM increments, as well as adjust automatic transmission shift firmness.

In addition, the Max Energy allows you to raise the top-speed limiter to match the speed rating of factory-approved high-performance tires that you have installed on the vehicle, and adjust the rev limiter up or down 500 RPM in 100-RPM increments. Plus, the Max Energy Power Programmer reads, displays and clears diagnostic trouble codes (DTC).
