An automotive accessory that deactivates Active Fuel Management to keep all cylinders running for steadier power delivery and smoother driving. Drivers who tow or prefer predictable throttle response gain immediate confidence on the road. How compatible and reversible is CYTROBE AFM Disabler across different GM V6 and V8 models?
⚡ At a Glance
- • Engine Performance: All cylinders run continuously for smoother throttle response and consistent torque
- • Best for: Owners of GM V6 and V8 vehicles who want steady power and towing confidence
- • Not ideal for: Owners of 2019+ Silverado and Sierra with 5.3L/6.2L and 10-speed transmissions
Deactivates AFM so every cylinder remains active for consistent engine behaviour. Plug-in OBD-II installation, reversible design, and broad GM compatibility with specific model exceptions.
Consistent Power Delivery – Thanks to AFM deactivation
Active Fuel Management alternates cylinder operation to save fuel; disabling AFM keeps all cylinders engaged at all times. The result is steady combustion across firing events rather than periodic cylinder shutdowns.
Smoother acceleration and more predictable torque during towing or heavy-load driving. Drivers notice reduced surging and a more linear throttle response.
Quick Upgrade Without Tools – With OBD-II plug-and-play installation
Connection is made through the vehicle's OBD-II port, requiring no disassembly or special equipment. The plug-and-play approach activates immediately after connection without ECU reprogramming.
Installation can be completed roadside or at home in minutes, allowing immediate evaluation of performance changes. No specialist fitting or garage visit is necessary for setup.
Warranty-Friendly Reversal – With non-invasive, fully reversible design
The disabler interrupts AFM signals without altering factory settings or wiring, and removal restores the original configuration. No permanent modifications are recorded on the vehicle's hardware.
Original AFM behaviour returns once the unit is removed, helping to preserve warranty and resale value. Owners can trial the effect without long-term commitment.
