Need help ASAP...not hitting full boost!

[UHATEIT]

yeah see I don't think its because of the car being run VTA...because its running fine otherwise. And no, no cel. Did you reset the battery when you did it? I did...let it idle for a while, then took it for a drive after installing. Blocking the recirc pipe makes a huge difference in terms of how the car runs VTA.

for sure! Yeah when i was talking about vta months ago and how bad the cars runs vta, that was because I didnt plug the recirc tube! Now that tried it with the D battery in the recirc hose it doesnt run too bad. Its a harsh drive, as in the car seems to struggle a tiny bit and the car runs rougher when shifting gears. But I have a CEL that I need to check, but there is no low boosting like you were having.

Apparently on this one website on how to adjust a BOV, you can actually hold MORE boost when venting! Crazy concept. Here is the link:

So if you're not getting full boost, it shouldnt be from vta, it may be the valve isnt shutting all the way when you floor it and may need to be tightened or the rubber ring around where the plunger inside makes a seal at the bottom is leaking out. You arent mentionging you have a problems HOLDING boost, you are talking about not reaching full boost all together. So its probably not a problem of the valve leaking and not holding the pressure, it seems the pressure isn't there initially and can be leaking around the flange or the O-ring on the plunger that keeps it shut.
As phillyb said, you wont really feel the leak at idle, you mak need a friend to give it some gas and hold the pedal while feeling around the valve yourself for rushing air, or put a bag around the valve like a plastic grocery bag and see if it starts to get air in it or see the bag move meaning air is leaking out.

I sued a mirror while a friend pressed the gas to check this: The valve plunger shuts and blocks the hold when you hit the gas, the boost sucks it shut, the vac from the top hose is what tries to pull it up and open and does it when you let off the gas. What you SHOULD try, is put the bag over the empty vent hole and they have a friend hit the gas and see if the bag starts to suck in a bit, if it does, then your valve is not shutting all the way when you hit the gas and it is not having a full seal (could be that o-ring on the plunger) then the ring would need replacing or you may try tightening the top screw and seeing if it stops the bag from sucking in while having a friend press the gas.

alright guys...got an update!! Took her out tonight and romped on it some, and it looks like she is back to normal!! Don't know what the issue was...I put some new gas in it (it was near empty) and plus yesterday i redid all my boost tube clamps and inlet clamp and intake clamp and retightened everything and now she is back to normal. But, i think this blow off valve is legit, because in 4th, i hit right at 15-16 psi and did not spike ONE BIT. It went straight there and held steady. My old blow off valve, when I ran it in VTA, i would floor it, it would spike 18-20 and hit boost cut and the car would fall flat on its face. Now, with the new greddy, its not spiking one bit. Car ran great tonight!!! I think my tubes was loose on it. maybe I can stand to loosen the bov a notch or 2, but as of now, the car is back to normal.

I gotta ask....what was the temp? I just have an intake with stock BPV(freak) and I have noticed temp has A LOT to do with boost. 0-20 degrees I literally can't get more than 14 psi max. When it was warmer 30-60 degrees I would get 16-16.5 max. All my tubes, etc are tight.
