you can leave it vented with no problems at all, its just gonna omit some noise when its venting the prespool of the secondary

But yeah, it'll be fine. Make sure you plug up that hole in the intake though.

 

damn i just started reading this thread, and im pretty much having the same problem, with boost, of course im having a bunch of other problems too, like idle at 1500, i guess my lim gasket is done, but that boost issue, same thing for me, sometimes ill get no realy boost in 1st, 2nd, but if i let off the gas and get back on i can get about .8 .9 bar, so i guess about 9 or10 lbs...but anyways after 4000 or 4500 whatever my boost is over with, i get nothing good, at all,

 

If you're nonsequential then the crv acts like a blow off valve (assuming that you t'd the vacuum line for the stock bov).

well i already have the hole in the air filter where the abv was plugged in blocked cause i have a turboxs H-RFL bov

currently i have the crv vented

i guess ill leave it like that

 

Bringing this one back from the Dead...the 4500 RPM problem must be infamous

Symptoms

10 psi till 4500 then 5 psi or no psi, sometimes it read no psi then jumps to five, other time it reads no psi and then has like serious lag and climbs to 3 psi

Checked the IC couplers and everything no cuts or anything
Checked the Check valves all good

What else is there to check short of replacing all of the vacuum lines

 

I suggest going through this list of steps.

This is the best set of turbo control troubleshoooting steps I've found.

 

what does ccv...crv....tca..cc..and cr mean..?

 

ccv = charge control value
crv = charge relief value
cc = charge control
cr = charge relief



What makes 4500RPM boost problems infamous is the fact that many solenoids change their state at that point. Even a small malfunction in the system will show up on the boost gauge. It can be anything from:
- low transition
- no 2ndary boost
- low 2ndary boost

Its nice to study the link posted above and that big colorful vacuum routing diagram.
That way you know exactly what to look for/check when you experience problems.
