Boost problem

[high klicks]

Hi guys! Well this is my story , I have just recently did many upgrades including turbo and fuel management. I had the car producing boost and solid at 10 psi ,would do more but wanted to get my fuel trims figured out first . Wasn't having much luck with that so was running rich , then I leaned it out to much and started knocking bad, car after that would not boost more then 1.1 psi. Did compression check it isn't the greatest but above service limits. Got fuel trims changed and am not knocking but still little rich. Boost leak down test with compressor found leak at clamp fixed it still low boost then another test showed air coming from valve cover. Don't know for sure what this means ,suggestions appreciated. I did read but not sure but could stuck open egr valve cause this.

Check and make sure the arm that moves the wastegate flapper didn't fall off or that the flapper itself isn't stuck open.

checked flapper and arm seems good

Just an update on my problem , it turned out why I was only building up a 1.5 pounds of boost was the turbo was not spoiling up because of back pressure . Just replaced my resonator with a high flow one 1200 cfm flow . The one I pulled out only got a little over 500 cfm flow one the flowbench. works like a charm know.
