Stock 400 Piston Boost

I understand, but the start retard will not retard under boost. I'll need that for sure if I intend on using the cast pistons.
Again like was pointed out and I even pointed out I don't know how the wastegate and some of the other stuff for boost works.. The retard side could be activated by a window switch on a relay..
Start future can be unactivated or activated for a locked out distributor mainly...
