Filter is clean. Apexi panel, I have also tested with a BMC and k and n I have laying around. Same result. There is something else going on with my car because I never had an issue with holding boost before with the stock airbox. I'm suspecting the upper intake manifold gasket which I haven't had time to replace yet. Obviously the pod filter does flow slightly better than and unmodified stock air box and therefore is allowing the turbo to hold boost better although there is a problem somewhere. I find the sound of the pod to be hideous and annoying. Air box is my preference, just gotta track down the source of my issue.
