Hey guys I have a 16 FoST with an AP, green air filter and turbosmart dual port. I previously had the stock BPV fitted was getting a boost leak. I'm on the Cobb OTS stage 1 tune so I should be getting around 20 lbs of boost but I was only seeing 10-11 lbs. I checked every vacuum line I could trace leading to the BPV and Boost solenoid and found no leaks. I also took off the BPV and expected it and it seemed in good condition. But still was only getting 10 lbs of boost so I bought a turbosmart dualport and know I'm only getting 12 lbs. I have it set all the way to hard. I checked o-rings and the vacuum line and everything is good? Any help? While the car is spooling it sounds like the BPV is already leaking, this happened with both the Turbosmart and the stock BPV.
