Do you buy a device to turn off the AFM? do you have to change out valve lifters also? I am still new to this AFM and , would rather not have it.
I had a local performance shop turn it and the rear O2 sensors off (for the planned long tube headers with no catalytic converters). They did a few other small things, too. For $150 I got the AFM disabled and those few other improvements, so I'm happy. I think the Range plug-in thing is around $200, but it only disables AFM, nothing else. This is a temporary solution until I can delete the AFM by removing the components (lifters, valley cover, etc.) from the engine or just swap in a stock non-AFM engine.
