OK ACV removal problem

Ok.. so i tried to remove the acv and air pump today and when i finished i took her for a spin and out of no were......20 psi boost. what the hell is that about. i capped the acv.. removed the air pump and plugged the 3 vacuum lines that when to the acv. and i get a **** tone of boost. so i ended up having to put the acv back on just to get the thing to run normal. granted i still get a bit of boost creep since i havent ported my waste gate yet but its normal. so my question is what did i do wrong. and what do i need to do to successfully remove acv with no issues. my JDM airpump is no good so putting it back on is out of the question. and i dont have any cats so acv seems kinda pointless to keep

The ACV has nothing to do with the turbo. You either did something to the wastegate line, or the cold weather gave you some nice boost creep.

thats what i thought... so i checked the lines going to the waste gate and there was not a single line from the waste gate that was undone or messed with at all. i used an air nozzle to put pressure on the waste gate from the turbo duty solenoid and it opened the waste gate. then i applied pressure to the other line from the duty solenoid and the air exited from the check valve going to the tid. i also replaced the waste gate hoses since they were kinda old.
