Choosing a Performance Chip: Factors to Consider

When selecting a performance chip for your Volkswagen Jetta TDI, there are several factors that you should take into consideration. The first is the compatibility of the chip with your vehicle. Not all chips will work with all car models. Therefore, ensure that you choose one that is compatible with your Jetta TDI.

The next factor to consider is the price. Performance chips can range in price, with some costlier options offering a wider range of features. However, it doesn’t mean that these are necessarily the best options for your car. It’s advisable to do some research and compare the features, price, and warranty of different chips before making a decision.

Finally, the ease of installation is another crucial factor to consider. Some performance chips, like the RaceChip, are designed for easy installation, allowing you to install them yourself without the need for professional assistance.

Installing the Performance Chip: Step-by-Step Guide

Now that you have chosen the right performance chip for your Jetta TDI, it’s time to install it. Here’s a step-by-step guide to help you through the process:

  1. Preparation: Before starting the installation, make sure that the engine is completely cool. This will prevent any accidental burns. Also, ensure that the battery is disconnected to avoid any electrical mishaps.

  2. Locate the ECU: The Engine Control Unit (ECU) is the computer that controls the engine’s functions. The location of the ECU varies depending on the model of the car. In most Volkswagen Jetta TDI models, it’s typically found under the hood, in the engine compartment.

  3. Install the Chip: Connect the performance chip to the ECU. The instructions for this will vary depending on the type of chip you have purchased. Typically, the chip will come with a set of connectors that attach to the ECU’s wiring.

  4. Secure the Chip: Once the chip is connected, secure it in place. Some chips come with adhesive backing or may require zip ties to hold them secure.

  5. Reconnect the Battery: After the chip is securely installed, reconnect the battery, and start the car. If done correctly, you should notice a difference in the performance of your vehicle.

Post-Installation Consideration: What to Expect

After installing the performance chip in your Volkswagen Jetta TDI, you should expect a noticeable increase in power and performance. However, it’s important to remember that while a performance chip can enhance the car’s performance, it’s not a magic solution to all engine problems.

You should still maintain your vehicle properly, including regular oil changes and tune-ups. If you notice any issues after installing the chip, it’s advisable to consult with a professional. Also, remember to check your vehicle warranty. While most performance chips are designed not to void car warranties, it’s always best to verify.

In conclusion, installing a performance chip in your Volkswagen Jetta TDI can significantly boost your vehicle’s performance, power, and fuel efficiency. By following the steps outlined in this article, you can ensure a successful installation and enjoy the improved performance of your car.

Maximizing Performance: Using the RaceChip App and Fine Tuning

Once you have installed your performance chip, getting the most out of it involves some fine tuning. This is where the RaceChip App comes in handy. This application allows you to control the performance enhancement from your smartphone. You can switch between three performance levels – Efficiency for saving fuel, Sport for normal everyday use, and Race for maximum performance.

To start fine tuning, first connect your smartphone to the RaceChip via Bluetooth. Once connected, select your Volkswagen Jetta TDI from the list of available vehicles. Then, choose the desired level of performance enhancement. It’s advisable to start with the lowest level and gradually increase it to monitor your car’s response.

Remember, fine tuning isn’t just about increasing power. It also involves optimizing the air intake. The air intake system is a crucial part of your vehicle’s engine, supplying it with the necessary air for combustion. Upgrading your air intake system can further enhance the performance of your car in conjunction with the performance chip.

Consider installing a cold air intake system. Cold air is denser, allowing more oxygen into the combustion chamber for a more efficient burn. An improved air filter can also boost power by providing a better flow of air to the engine, increasing horsepower torque.

Customer Service and Warranty Considerations

One of the advantages of choosing a RaceChip is the excellent customer service provided by the company. If you run into any trouble during the installation process or whilst fine tuning, the customer service team can provide assistance. They can troubleshoot any issues and provide guidance to ensure that you’re getting the most from your performance chip.

Moreover, a significant concern for many car owners is whether the installation of a performance chip will void the engine warranty. With RaceChip, this is typically not the case. The company states that its products are developed in such a way that they do not interfere with any vehicle components which would result in the voiding of your warranty. Still, to avoid any doubt, it’s best to check with your car manufacturer.

Remember, free shipping is usually included when you purchase a RaceChip, reducing the overall cost. Plus, the RaceChip GTS comes with a 5-year product warranty, providing added peace of mind.


Installing a performance chip can be a game changer for your Volkswagen Jetta TDI. It’s a process that can greatly increase your car’s fuel economy, power, and overall performance. The RaceChip, in particular, offers a practical, cost-effective solution to boost your car’s capabilities, and with the RaceChip App, you can easily fine tune your car’s performance to suit your driving needs.

Whether you’re looking for increased throttle response, improved fuel economy, or simply wanting to achieve maximum performance, a performance chip can help you reach these goals. Just be sure to follow the correct installation process, keep your car well-maintained, and use the available tools like the RaceChip App for fine-tuning. Happy driving!
