Not Boosting Past 5 Psi... Tcv?

Hey guys!

 

So I wanted to ask you what might be the problem with my car... 

 

I have a boost controller installed, it runs at about 18-22 vac, but won't boost past 5 PSI! It boosts right up to 5 but won't go any higher. Just wondering what might be the problem here. I am thinking it might be the stock TCV, I have heard that they aren't great on these cars, is that a possibility? I can't hear a vacuum leak at all, and I have gone through and tightened a lot of the clamps for vacuum hoses. 

 

If it is the TCV, I was just going to go down to IPD and buy the HD one they sell.

 

Thanks,

 

Max


One thing I forgot to mention, it isn't throwing any codes at me.
