If you’re a proud owner of a GMC Sierra, you already appreciate its powerful performance and reliability. However, you may have wondered if there’s a way to unleash even more power from your truck by removing the governor.
The governor is a device that limits the top speed of your vehicle for safety and legal reasons. While tampering with the governor is not recommended, we understand the desire for increased performance and want to provide you with information on this topic. To remove the governor on your GMC Sierra, you would generally need specialized tools and advanced knowledge of vehicle electronics.
In this blog post, we’ll explore removing the governor on your GMC Sierra, discussing the advantages and potential risks involved.
How To Remove Governor On GMC Sierra?
Modifying your GMC Sierra’s governor can provide higher speeds but poses risks and may void warranties. Here’s a step-by-step guide to removing the governor, acknowledging the potential consequences.
Step 1. Understand the Risks and Legalities
Removing the governor can lead to unsafe driving conditions and damage to your vehicle. Research local laws to ensure compliance and be aware of potential legal consequences.
Step 2. Gather Necessary Tools
To access and modify the governor, you may need tools like a socket set, wrenches, screwdrivers, and possibly a laptop with appropriate software if you plan on reprogramming the engine control unit (ECU).
Step 3. Locate the Governor
The governor is typically located within the engine bay near the throttle body or connected to the ECU.
Consult your vehicle’s manual or online resources for specific details regarding the governor’s location in your GMC Sierra model.
Step 4. Disconnect the Battery
Before working on any electrical components, disconnect the battery’s negative terminal to prevent accidental short-circuits or electrical damage.
Step 5. Remove Engine Covers
If your GMC Sierra has engine covers, carefully remove them to gain access to the governor and related components. Follow the manufacturer’s instructions or consult online resources for guidance.
Step 6. Identify the Governor Components
Locate the throttle position sensor (TPS) and any wiring connected to the governor or speed limiter. Take note of their positions and connections for future reference.
Step 7. Disconnect and Modify the Governor
Using the appropriate tools, carefully disconnect the wiring and connectors associated with the governor.
Depending on the specific model and setup, you may need to remove bolts or screws holding the governor in place.
Step 8. Disable or Modify Speed Limiting Mechanism
Once the governor is accessible, determine the method used to restrict speed. This can involve adjusting a physical mechanism, reprogramming the ECU, or employing other techniques.
Follow specific instructions for your GMC Sierra model.
Step 9. Reconnect and Test
After modifying the governor, reconnect all components and wiring as they were before. Reconnect the battery and start the vehicle to ensure it operates correctly.
Conduct a test drive to verify if the governor has been successfully removed.
Step 10. Consider Reputable Tuning Options
Instead of completely removing the governor, consider reputable aftermarket tuning options.
These allow you to adjust the speed limiter while maintaining safety and reliability. Consult with professionals to explore these alternatives.
Alternative Methods To Increase The Speed Of A GMC Sierra Without Removing The Governor
If you’re looking to enhance the speed or performance of your GMC Sierra without removing the governor, there are alternative methods to consider.
These methods can help improve acceleration, handling, and overall performance while maintaining your vehicle’s safety and legal compliance. Here are some options:
Performance Tuning
Investigate reputable aftermarket tuning options specifically designed for your GMC Sierra model.
Performance tuners or programmers can optimize the engine’s parameters, such as fuel delivery, ignition timing, and throttle response, to enhance performance within safe limits.
These devices are often plug-and-play and can be easily installed and removed without permanent modifications.
Cold Air Intake
Installing a cold air intake system can improve engine performance by increasing airflow and reducing intake air temperature.
This allows the engine to breathe more efficiently, resulting in enhanced power and throttle response. Cold air intake systems are available as aftermarket components designed to fit your GMC Sierra’s engine.
Upgraded Exhaust System
A performance exhaust system can reduce exhaust backpressure, allowing the engine to expel gases more efficiently.
This can lead to increased horsepower and a more aggressive exhaust note. Consider installing a cat-back or axle-back exhaust system specifically designed for your GMC Sierra model.
Suspension Upgrades
Enhancing your vehicle’s suspension system can improve handling, stability, and cornering performance.
Upgrading components like shocks, struts, springs, sway bars, and bushings can provide better control and responsiveness without affecting the governor or speed limits.
Tires and Wheels
Opt for high-performance tires that offer improved traction, grip, and handling characteristics.
Additionally, lighter alloy wheels can reduce unsprung weight, enhancing acceleration and responsiveness.
Regular Maintenance
Ensure your GMC Sierra is properly maintained to keep it in optimal condition. Regularly change the engine oil, check and replace air filters, maintain tire pressure, and adhere to the recommended service intervals.
A well-maintained vehicle can perform better and provide a more enjoyable driving experience.
Driver Skills and Training
Investing in driver skills and performance training can significantly improve your driving technique, allowing you to maximize the potential of your GMC Sierra within legal limits.
Advanced driving courses can teach you how to handle your vehicle more effectively and extract the best performance while maintaining safety.
Potential Risks and Consequences of Removing the Governor
Removing the governor from your GMC Sierra can lead to several potential risks and consequences that you should be aware of before proceeding with any modifications. These include:
Safety Hazards
By removing the governor, you increase the vehicle’s top speed capability, which may exceed what the vehicle’s braking, suspension, and handling systems are designed to handle.
This can lead to a higher risk of accidents and loss of control, especially if you are inexperienced or unprepared to handle the increased speeds.
Mechanical Damage
Driving your vehicle at higher speeds than it was designed for can put excessive strain on various components, including the engine, transmission, brakes, tires, and suspension.
This can lead to accelerated wear and tear, increased maintenance requirements, and potential mechanical failures that can be costly to repair.
Voiding Warranties
Modifying or tampering with the governor can void your vehicle’s warranty. If any issues arise in the future, the manufacturer may refuse to cover repairs or replacements due to the unauthorized modifications.
Legal Consequences
Removing the governor may be illegal in your jurisdiction. Many countries and states have laws and regulations in place regarding vehicle modifications, including speed limiters.
If caught driving a modified vehicle, you may face fines, penalties, or even legal action.
Insurance Implications
Modifying the governor can also have an impact on your insurance coverage.
Insurance companies typically base their premiums and coverage on the assumption that your vehicle operates within certain safety parameters.
Modifying the governor may result in policy cancellations, increased premiums, or limited coverage in the event of an accident.
Resale Value
Removing the governor can significantly affect the resale value of your GMC Sierra. Potential buyers may be hesitant to purchase a vehicle that has been extensively modified, and those modifications can negatively impact its market value.
