Power Tuning

Hypertech Power Tuning

Here at Simpson, we offer Hypertech’s Power Tuning System. Stop in and we can install it for you as well!


Higher compression ratio engines and engines with superchargers or turbo chargers were designed to use only premium octane, so only one (1) Power Tuning program for premium octane is provided. But, if your car or truck came from the factory capable of using more economical regular octane, then two (2) optimized tuning programs are provided: one for premium, and the other for regular. In most cases, Hypertech’s exclusive Power Tuning for regular octane provides excellent power gains, almost as much power as premium octane. If you are using premium octane, and you want all-out, maximum power, then select premium octane Power Tuning.

E-85/Flex Fuel Vehicles

We recommend premium octane tuning for vehicles using E-85 fuel. The improved engine tuning will increase the part-throttle efficiency and wide-open throttle performance compared to the factory tuning.

Diesel Vehicles

Three (3) stages of Power Tuning are available. Even the highest power level, Stage 3, maintains safe EGTs while towing the maximum weight specified by the vehicle’s manufacturer. No other tuner offers this level of power for towing. Hypertech’s low EGTs, proper transmission shifting and superior tuning that doesn’t require de-fueling, giving the Max Energy Power Programmer the performance advantage. In the aftermarket automotive industry, it’s very typical to see performance parts improvements measured by a dynamometer (dyno for short). But what is a dyno, and what does a dyno graph mean to you? Essentially, a dyno is just a tool to measure how much power and torque a vehicle makes at wide open throttle as the engine sweeps through an RPM range. By comparing changes back-to-back, the improvements can be recorded and displayed for reference. There are two (2) different dynamometers for measuring power increases, and their measurements are a bit different. One type is an engine dynamometer which measures the power and torque of an engine on a stand outside of the vehicle. This is typically done in a facility that has a separate room just for the engine stand and dynamometer setup. The engine dyno measures exactly what the power and torque coming from the engine is at all of the RPM points. Engine Dyno numbers are what vehicle OEM’s quote for power. The other type is a chassis dynamometer which measures power and torque at the tires during the RPM sweep. The power measured at the tires on a chassis dyno does not account for the power lost through the spinning of the drivetrain (transmission, driveshaft, differentials, axles, wheels, and tires). Because of this, chassis dyno power and torque measurements are lower than engine dyno numbers by roughly 10% to 20%, or more in some cases. The benefit is that the chassis dynamometer shows the true power that a vehicle is putting to the ground.
