Bottom Line The LS1 certainly responded well to both our Hypertech and Morgan Motorsports upgrade package. And if you’re running a stock application, the PP3 will definitely give you additional horsepower by adding more timing and leaning out the air/fuel ratio. However, should you decide to step it up a notch and add even more modifications, then the PP3’s other features really make the unit shine. The PP3 allows you to program gear ratio changes into the computer to correct speedometer readings, operate the electric fans earlier, and raise the rev limiter.

Gas Is Gas... Right? Depending on where in the U.S. you reside, your state may enforce the use of reformulated gas (RFG). RFG is a special blend of gas that has been supplemented with ethanol and methanol fuel oxygenates to help turn your vehicle emissions into a less-harmless and more eco-friendly carbon dioxide. Conventional non reformulated gas (non-RFG) uses hydrogen and carbon, which produce poisonous carbon monoxide. While RFG fuel is better for the environment, it can be detrimental to performance vehicles since these oxygenated fuels essentially lean out the air/fuel ratio. This might not matter if you’re driving with the factory-supplied hardware, but when you start bolting on aftermarket goodies you may soon hear your pride and joy detonating like a can of marbles.
