FullPower AFM/DFM Disabler
Stop AFM From Destroying Your Engine
Prevent costly lifter failures and lock your engine in full V6 or V8 power mode instantly. Protect your truck for less than the cost of a tank of gas.
Save Thousands in Engine Repairs
The Active Fuel Management system cycles special lifters on and off hundreds of times per drive. When a lifter fails, the camshaft gets damaged, and metal debris spreads through the engine, resulting in repair bills averaging $6,000. Here is how fixing it compares:
Physical AFM Delete
$3,000 - $6,000+
- Requires major physical engine work
- Takes 1 to 2 days in a mechanic shop
- Non-reversible modification
- Void risk on factory warranties
AFM/DFM Disabler
$35.95
- Installs in exactly 10 seconds
- Zero tools or mechanical knowledge needed
- 100% reversible—simply unplug it
- Zero risk of permanent ECU changes
Installs in 10 Seconds. No Tools. No Mechanic.
Most fixes require expensive tools or risky engine modification. The Disabler bypasses the complexity by plugging straight into the factory OBD2 port under your driver's side dashboard. It instantly locks your vehicle in full V6 or V8 mode the moment it's connected.
No ECU Modifications & No Fault Codes
Unlike software flashes, this device leaves absolutely no traces on your vehicle's engine control unit (ECU). It triggers zero diagnostic codes and won't affect standard vehicle computer processes. Unplug it at any moment to return your truck back to factory stock.
Drives Smoothly & Stops Oil Consumption
Eliminate the noticeable engine shudder when cruising and cylinder deactivation lags. By keeping your engine in constant full-power mode, you stop oil from being pulled past the piston rings on deactivated cylinders, drastically reducing oil consumption between service changes.

Frequently Asked Questions
💡 Does this device make permanent changes to my vehicle?
No. It does not write any permanent changes to your computer. It only works while plugged directly into your OBD2 port. As soon as you unplug the device, your vehicle instantly returns to its original factory configuration.
💡 Will this trigger warning lights or error codes?
No. The disabler runs cleanly in the background without triggering diagnostic trouble codes (DTC) or warning lights on your instrument cluster dashboard.
💡 How does this stop my truck from burning oil?
When cylinders are deactivated by the AFM system, oil gets pulled past the piston rings and burns inside the unused combustion chambers. Keeping your engine locked in constant full-power mode eliminates this drop, stopping the engine oil loss between changes.
