Our read on this product
This module bypasses a fuel-saving feature in certain GM vehicles to restore consistent V8/V6 power. It’s a plug-and-play solution for drivers who find the automatic cylinder deactivation less engaging or worry about potential long-term engine wear. The primary benefit is regaining full engine power and a smoother, more consistent driving feel without altering the vehicle's factory settings.
It addresses common complaints about AFM systems, such as inconsistent power delivery and the potential for increased wear on components like valve springs. Because it's a simple OBD-II port connection, installation is straightforward and reversible, meaning you can remove it without leaving a trace, which can be important for maintaining vehicle warranty.
What makes it stand out
- Restores consistent V8/V6 power delivery compared to systems that automatically switch cylinders.
- Offers a non-invasive, plug-and-play installation that is easily reversible, unlike permanent tuning solutions.
When this isn't the right fit
- Not compatible with all GM trucks, specifically newer Silverado and Sierra models from 2019 onwards.
- If your vehicle is parked for extended periods, you'll need to disconnect the module to prevent potential battery drain.
Real-world notes
- The four LED lights illuminate when the vehicle is in motion, indicating the AFM system is disabled and the engine is running in its full V8 or V6 mode.
- When the vehicle is stopped, two of the four LED lights remain illuminated, showing the device is in standby but still active.
Consider this if you own a compatible GM V6 or V8 and want to disable the AFM system for improved performance and engine feel.
