MoPower Calibrations developed the 2015 Chrysler 300 5.7 calibration gains up to 25whp and 30ftlb of torque at the wheels across the curve, giving you thrill of increased performance while driving your Chrysler 300.

We started the development by taking a stock 5.7L to get a baseline (Shown in the dyno graph below). Once we had the baseline pull done we begin developing the performance calibration with the thought of increased power and torque while maintaining safety and reliability. Below is a brief list of the areas we focused on in the calibration during development.

• Increased Throttle Response
• Increased Low-end Horsepower/Torque
• Increased WOT Horsepower/Torque
• Increased Fuel Economy
• Increased WOT Horsepower/Torque
• Modified Spark/Fuel Curves
• Modified Torque Management Algorithms
• Modified Knock Thresholds

MoPower Calibrations Chrysler 300 5.7L Performance Tune was developed on Premium Fuel (92 Octane). We have modified our tune to work with 91, 92, and 93 octane fuel. Please Select the desired octane fuel you plan to run prior to checkout. Use of lower octane fuel may result in damage to the engine and MoPower assumes no liability for damage due to incorrect octane fuel used.
