Jet Performance Products

Your engine has amazing amounts of power potential just waiting to be unleashed. And, the fastest and easiest route for turning that potential into raw horsepower and torque is by tapping into your vehicle's computer with the new Jet Performance Programmer.

You'll be able to modify your Chevy, GMC or Cadillac's air/fuel ratios, ignition, shift points, shift firmness, top speed limiter, and rev limiter specs. Or, leave the fine tuning in the hands of the pros and use the module-style Jet presets.

The Jet Performance Programmer also lets you access, read and clear diagnostic trouble codes. Plus, you can even use the Jet Performance Programmer to calibrate your speedometer. Settings for regular, mid-grade and high octane fuel, too!

The Jet Performance Programmer installs in minutes. Programming takes less than 20 seconds and your engine can be returned to its stock settings in about 5 minutes. Your Jet Performance Programmer is backed by a 1-year warranty.

Notes

  • Jet suggests using 91 or 93 octane gasoline to achieve stated maximum power gains with the Performance Programmer
  • Flex Fuel Vehicles: fueling with E85 is not recommended in conjunction with your Jet unit. Burning E85 reduces efficiency and power compared to using gas, which nullifies the effect of Jet's programming.

Contact Southeast Performance for details and pricing.
