  • Performance Promise vs. Reality

First and foremost, let’s talk about the elephant in the room – the performance boost. Stealth Modules claim to offer a significant increase in horsepower, torque, and fuel efficiency.

However, the actual gains can vary significantly depending on the truck’s make, model, and existing modifications. Some users report impressive improvements, while others are left underwhelmed by the results.

This discrepancy can lead to frustration and a sense of buyer’s remorse.

  • Installation Woes

While Stealth Modules are marketed as easy to install, this isn’t always the case. Some users have reported difficulty in locating the proper connectors, while others have experienced issues with securing the module in place.

The unclear instructions and occasional lack of vehicle-specific guidance can make the installation process a headache for even the most seasoned DIY enthusiast.

  • Potential Damage to Your Truck

One of the most concerning problems with Stealth Modules is the potential for damage to your truck’s engine and transmission. Since the module alters the engine’s parameters, it can lead to unintended consequences, such as increased exhaust gas temperature, which can cause significant wear on engine components.

Additionally, the added torque can put extra strain on the transmission, potentially causing it to fail prematurely.

It’s essential to research your specific vehicle and understand the potential ramifications before installing a Stealth Module.

  • Quality Control and Reliability

While many Stealth Modules are well-built and reliable, some users have reported receiving defective units or experiencing issues with the module’s performance over time. These concerns highlight potential quality control issues that can be frustrating and costly for truck owners.
