Boost/Vacuum Issues

celiguy00 · 01-30-2014, 10:28 PM

Ok so I am still new to this FD I got over here in Okinawa Japan. When I purchased the car it would boost to 10 like is suppose to, but now it won't boost past 6. It has an HKS boost controller but it is doing nothing at the moment. I did replace a tube that was broken just under the intakes that was hooked up to the boost controller. Now it makes a weird sound when it comes off boost. After talking to a friend he said it sounds like thats air not being released and it is going back toward the turbo? So my thought is possibly the stock air bypass valve or charge relief valve?

Any thoughts? Thanks
