AFM/DFM disabler is the kind of simple, plug-in workaround people reach for.
Honestly, itâs basically for folks who just want their engine to stay in the mode they expect.
What this AFM/DFM disabler is for
This AFM/DFM disabler is designed to help keep your engine in V6/V8 mode at full power all the time,
based on the product description. Itâs meant to be used with compatible GM vehicles and is described as a
no-tools, plug-in setup via the OBD-II port.
Quick compatibility heads-up
The listing says it doesnât fit 10-speed transmission models and 2022+ refresh models.
It also asks you to check compatibility with your specific vehicle before buying.
(Thatâs good adviceâAFM setups can be picky.)

and donât want to mess with ECU programming.
Itâs basically a âkeep it simpleâ option: plug in, use it, and unplug when you want to go back to factory defaults.
Best Fit For
