Ok will do that tomorrow and see how it goes it's getting a bit late now, yep I followed a firing order and they are correct, Should it still run without blocking off that hose it's the one come from behind the boost actuator it's kinda hard to see until your up close, The front one is plugged in and plugs into under where the other fuel pressure regulator line goes

Yeah they normally still run just a little rough. Just leave the one going from the actuator to the charger and the one to the fuel reg but block the one off that’s next to it. That gets rid of the boost solenoid altogether. Hope you understand this.

Ok too easy, what about the other one on the actuator that's hard to see until your up close it has an angled piece on it but goes to nothing, the fuel reg line is on and the one next to it blocked off

And the third one that connects to the charger in still on all up there's one from the boost actuator that has an angled vac line piece on it but it's just sitting there and not doing anything the air I'm hearing is probably coming out of that one, Still trying to get my head around all of this, lol, Sorry

And just to clarify only one vacuum line gets blocked in the whole system or 2 ?

Just one. Block it off right on the black junction that is bolted onto the charger.

Ok yep got that one blocked off at that same black junction where the fuel reg vac line goes also, There's only that one vac line left, Do people just leave that one off when they do the L67 top swap because I can't see where it could plug into..

Do you mean the one you pull off? Cause that one can just stay free or in the bin.The other one that goes onto the bottom of the actuator gets the same treatment and just leave the bottom port on the actuator open.
