Honestly, after doing the research, GM states that AFM really only offers up to 12% efficiency increase..which means in reality..it's probably closer to 7%.

as far as efficiency goes i thought 7% is monumental.

Not afraid of mods, but I think it would be a waste to get rid of AFM valves just because the aftermarket is currently ignoring proper support or hasn't developed it yet. As I have no current plans for a radical camshaft in the near future, I see no reason to disable AFM
