Hypertech Power Tuning
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.
