Removing the speed limiter on a Dodge Charger can be a tempting modification for enthusiasts looking to unlock their vehicle's full potential. However, this process involves technical steps and significant considerations regarding safety and legality. This guide will provide you with the necessary information to understand how to approach this modification responsibly.

Understanding the Speed Limiter

The speed limiter in your Dodge Charger is designed to prevent the vehicle from exceeding a certain speed, typically set by the manufacturer for safety reasons. This limit is often influenced by factors such as:

  • Tire Ratings: The tires equipped on your vehicle have specific speed ratings, and exceeding these can lead to tire failure.

  • Engine Protection: Limiters help protect the engine and transmission from damage that could occur at high RPMs or speeds.

Before considering removal, it's crucial to understand these implications and ensure that your vehicle is equipped to handle higher speeds.

Methods for Removing the Speed Limiter

There are a few methods to disable or modify the speed limiter on a Dodge Charger:

1. ECU/PCM Reprogramming

Reprogramming the Engine Control Unit (ECU) or Powertrain Control Module (PCM) is one of the most effective ways to remove the speed limiter. This can be done using specialized tuning software or devices. Here’s a basic outline of the process:

  • Obtain an OBD-II tuner compatible with your vehicle model.

  • Connect the tuner to your car’s OBD-II port.

  • Follow the instructions on the device to access and modify the speed limiter settings.

  • Important: Ensure that you have a backup of your original settings in case you need to revert back.

2. Performance Tuners

Aftermarket performance tuners, such as DiabloSport or SCT, can also be used to adjust speed limits. These devices allow you to upload custom tunes that can disable or raise the speed limiter.

  • Purchase a performance tuner from a reputable source.

  • Use it according to the manufacturer's instructions to adjust your vehicle’s settings.

3. Professional Tuning Services

If you're not comfortable with DIY methods, consider hiring a professional tuning service. These experts can safely modify your vehicle's ECU settings without risking damage.

Important Considerations

Before proceeding with any modifications, keep these points in mind:

  • Warranty Implications: Modifying your vehicle may void any existing warranties.

  • Legal Issues: Removing speed limiters can have legal ramifications depending on local laws and regulations regarding street legality.

  • Safety Risks: Ensure that your car is equipped with appropriate tires and safety features to handle increased speeds.
