What your wanting to do isnt something as simple as changing some tables. It most likely cant even be done using efi live or any tuning software due to hard coding in the back ground. AFM is horrible and the lifters will fail, its just a matter of when they will fail. There is no way I wold go out of my way to keep AFM when by deleting you can gain hp and fuel mileage and as a bonus a lifter wont break and take out your engine.
