[240waters]

i just got the car its a 92 s13 with a sr.it has a apexi avcr and the way the vacuum is ran is the valve is hooked to to the wastegate and i know thats correct but on the other end of the valve the line is T'd and on one end of the T its has the apexi device that reads the boost but on the other end of the T the line is ran to the nipple on the bottom of the throttle body.. i dont think this is correct .. thats not a good vac source even if its surpose to go to a vac source.. those are surpose to be capd off under the TB where the stock canister used to go .. and my autometer mechanical boost gauge is T'd to the BOV line which is hooked to the intake manifold next to the fpr line... What is all wrong with this setup and what do i need to change .. help is greatly apreciated .. should'nt the other end of the boost valve be hooked to the hot pipe or to the turbo outlet where the hotpipe is connected.. and then other end goes to the wastegate.thanks for any help once again
