EF3 slow spool? Help!
Im getting my car tuned and my EF3 is very lazy. Its on WG pressure (22psi Turbosmart) and its not hitting 23 psi til 5k. I need someone to point me in the right direction. I'm adjusted my WGA then checked with Evoscan its picking up a few psi each time but now I have the WGA rod all the way down and its still slow. I have checked and rechecked for boost leaks. Car is built 2.0 with only around 2k on it. I was told maybe an exhaust leak but don't really know how to check that as there is nothing audible. Any help is appreciated. Im extremely frustrated. Thanks

SD, EF3 w/ anti surge, S3's, megan manifold (oddly don't think this is the culprit), ebay o2? Im doing a boost leak test and even at 80psi on my regulator the boost is only showing like 20psi. No leaks audible or otherwise. Outlet pipe all the way to TB, have a small one on the MAP sensor. Could a bad flapper cause this?

got EVERYTHING apart and the flapper looks to seal fine. I took it in a pitch black room and shined a light into the flapper side and no light was coming through. So Im out of ideas. The gasket from the mani to turbo did have a few small cracks on the inside. I thought it might not even be worth mentioning, ill post a pic.
