Take Control Of Your V8 The Way It Should Be

If you just picked up a new Silverado, Sierra, or full-size GM SUV and want your V8 to actually feel like a V8, the Range Technology RA007 DFM Module is the upgrade you need. Straight from the factory, the DFM system is constantly cutting cylinders, creating that sluggish, inconsistent driving feel that frustrates a lot of truck and SUV owners. This module shuts that down, giving you all eight cylinders, all the time, with smoother power delivery and a noticeable improvement in drivability. It also disables the Auto Start/Stop system, so your engine doesn’t shut off at every red light or stop sign. That means no more lag off the line or annoying power interruptions to your A/C or rear entertainment systems. With a plug-and-play design that connects directly to your ECM, it installs in minutes and leaves no trace when removed. Whether you're towing, daily driving, or just want peace of mind that your engine is working the way it should, this is one of the smartest upgrades you can make.

Full V8 Power Designed For Refresh Model Control

The RA007 DFM Module is built specifically for late-model GM platforms, including 2022.5–2025 Silverado and Sierra 1500 Refresh trucks and 2021–2024 full-size V8 SUVs like the Tahoe, Yukon, Suburban, and Escalade. It’s the first-to-market solution engineered to work with the newer Global B electrical architecture and provides reliable suppression of Dynamic Fuel Management and Auto Start/Stop systems. Installed directly at the ECM using smart inline technology, the module allows your engine to operate in full V8 mode at all times without reprogramming the ECU. This preserves your vehicle’s warranty and allows a true return-to-stock condition when the device is unplugged. During extensive testing, engineers found that while coasting with 0 percent throttle, some applications may still engage 0-cylinder mode to maintain safe drivability and prevent unwanted fuel economy drops or braking concerns. Unlike tuners or reflash tools, this solution is fully emissions compliant in 49 states and pending approval for 50-state CARB compliance. It’s a clean, hardware-only fix for drivers who want consistent performance and long-term engine protection without the compromises of factory programming.
