Superchips has just released their programmers for the 2007 300C, Charger and Magnum with the 5.7 motor!



The Superchips’ FLASHPAQ handheld tuner
is a sophisticated but easy to use engine management tool
designed to deliver extraordinary power and torque gains,
unparalleled transmission controls and improved fuel economy.
How it works - Superchips tuners plug directly into your vehicle and read the stock calibration stored in your vehicle. A stock calibration is the set of fuel, spark and transmission settings that the dealer installed in your vehicle at the time of sale. After reading this file and saving it to your Superchips tuner, the hand-held device then downloads the Superchips’ calibration to your vehicle. All engine and vehicle operations work exactly the same, except your engine will now work more efficiently - which equals more power, more torque and better mileage.

Benefits include:
Improved Horsepower and Torque
Easy Installation - No Tools Necessary
Improved Fuel Economy
Optimized Drivability
Diagnostic Trouble Code Reading Capability
Torque management reduction
Ability to recalibrate the speedometer after a gear/tire size change

NOTE: Superchips tuners are designed for use on stock vehicles only (i.e., no engine or transmission modifications). The use of Cold Air Intakes and Exhaust Systems is allowed for most applications. Please call Customer Service with any questions or concerns.
