What's the difference between Stage 1 and Stage 2 Power Tuning?
JET Performance has two types of tuning available for some vehicles
depending on the modifications to the vehicle vehicle. The JET stage 1 is
programmed for maximum power increases on a stock vehicle. The JET stage 2
is designed for peak horsepower in cases where the engine has been modified
to run cooler and the exhaust system is less restrictive than stock,

If JET Performance Power Tuning is so great, why didn't the factories do it
that way?
The factory program is designed for the average driver and is set to take a
wide variety of operating conditions and driving styles into consideration.
Consequently, stock calibrations aren't set to provide maximum power
because they have to accommodate drivers who may use poor quality gasoline.
For a real hi-performance person, premium is all they put in their vehicle.
At JET Performance, we optimize the spark and fuel curves over the entire
RPM band from just off idle right up to the redline for maximum power and
performance from the best gasoline.

Can I run regular gasoline?
No. All tuning is designed and calibrated for 91 or higher-octane fuel. In
some cases 89 octane may be used.
