I am trying to troubleshoot a boost issue with my FD. Primary boost is great. Secondary boost is irregular. It will not run a 10-8-10 pattern but after driving around, changing gears, etc. I will sometimes get secondary boost.

So I took off the upper intake manifold and started reviewing the hose diagram. Immediately I was in shock because it appeared I did everything wrong. But I questioned myself saying there's no way I did that bad of a job. So I searched again for diagrams & then I found a different hose diagram and it matches up as far as I have traced. So is there a correct simple sequential diagram and an incorrect one?

My current setup (found this on rx7club):


This is the one I found and thought I did everything wrong:


Differences between the two I have found:
The solenoid "on top" is different (1st diagram is marked as Charge Relief (H), 2nd is Turbo Control (E)).
The two solenoids in row are not the same two and are in different order: (F&E vs. H&F).
2nd diagram's Y-pipe hose connects to nothing. (Yellow hose)

 

In the 2nd diagram, The yellow hose that goes from the y-pipe that "appears" not to connect to anything actually connects to the pressure chamber, in the image it is the yellow line that has the check valve and that goes "through" the upper intake manifold.

 

if you followed the diagram then you did it correctly. there isnt a "wrong" way to do it. there are alternate methods but so long as you follow whatever diagram you use then it is correct.

did you replace all your hoses with silicone? if you are having intermittent irregular secondary issues then youre issue may not vacuum related. i would check your actuators and the two green solenoids on the front of the uim. not saying that youre ISNT vacuum related but keep your possibilities open before you spend all your time shooting hoses...

 

Sorry I did not update this thread, but rather the one I linked to not the original post.
Either I had a bad solenoid that was testing ok or the turbo control solenoid is different somehow than the others or I had a line mixed up somewhere before putting it back together.
Everything is boosting perfectly now.
