When you remove a restriction in the MAS(combs) you are letting more air in, but not all of it is being metered. That is why it leans out your car, b/c more air is getting in and not being metered. That is why he can richen his AFC and get timing retard.
The vette guys gut their MAFs to run a little leaner b/c factory settings are a bit rich.
So multiades, he is correct when he says that you can richen the AFC when gutting the MAS. You see, not all the air is being metered, so there is no correction at the MAS as you stated, there is only the AFC correction.
