About a month ago I installed a Blitz DD BOV venting to atmosphere along with an HKS EIDS Type K. I know I know.... . But yeah, I had some problems, the Evo would only hit about .5 to .6 bar of boost tops. Then about a week later, I was boosting normally like stock up to 1.5 bar topping out at about 1.7 peak occasionally, according to my boost gauge.....just like it did when I bought it. Things were going great then BAM back to the .5 bar of boost again. So today I took out the EIDS and the BLITZ BOV and I put in an HKS SSQV recirculating and everything is stock except for the cat back. I put my hand up to the filter and I feel no air going in and the exhaust is SUPER quiet even with no silencer and I can barely feel any kind of exhaust coming out of the tip. What is the problem? Any help would be appreciated. I'd take it to the dealership to have it checked out but I don't trust them plus someone broke off the vaccuum line on my stock bov. I've posted this on NorcalEvo but didn't get much of a response. Hopefully you guys will have more input. Thanks in advance.

What Im running(nothin special):
HKS SSQV (Recirculating)
Blitz DTT
Blitz Boost Gauge
Catback exhaust

What I've checked:
Yes, the BOV is recirculating
Yes, the BOV is installed right, its not backwards
Intercooler hoses/clamps
BOV hoses/clamps
Intake hose/clamp
Vacuum hoses to BOV and T-fitting to boost gauge
Wiring from EIDS to ECU patched up

 

anyone???

 

Well it looks like no one has any ideas. I was hoping yous guys would be lot more help.
