Ok so I did a little research on check valves since I have to wait for my missing link for 2+ weeks since its on back order I needed something to run my car with until then. So I found some threads about them I made mine look like this



It seems to work ok I used 4 check valves which alot of ppl say they use any where from 1-3 normally. But still under WOT it will still detects boost like its not releasing enough pressure from them. I got the black tetra ones from the pet store. Any ideas? the check valves are way better then no check valves but I thought these were suppose to fix my problem competely specially since I am using 4

 

I've seen a set up with 6 of them in, try adding another. there is a lot of air to release for it not to see any boost.

 

That is the correct way to run check vavles.

I seen people just run them like..

TTTTT

Which is most certainly wrong.
