Full Product Description
Stop the annoying “switching” between 4 and 8 cylinders with the Range Technology RA003G. For many GM owners, the factory cylinder deactivation system leads to sluggish throttle response, exhaust drone, and long-term mechanical wear on lifters. The RA003G is a patented solution that keeps your engine in full power mode at all times, providing a smoother, more predictable driving experience.
The Green LED model provides a subtle visual confirmation that the device is active. Unlike handheld tuners, this module does not reflash the computer; simply unplug it to return your vehicle to 100% factory settings. It is the perfect tool for towing, hauling, or simply enjoying the consistent power your truck was built to deliver.
