Knock Knock Whos There???

[dank GN]

Well to start off i have my fuel pressure set to 40psi with vacuum line off.Every time i get in to it it goes really lean like 700 O2 .I have my alky turned up to 7 to keep me from knocking. I just cant figuare out y i am running so lean?? my fuel pressure goes up 1psi to 1 pound of boost. i have to keep my alky kit setting to 7 if i dont want to any knock. so if any one can shoot me some ideas on what may be going on with this problem i have it would be greatly apprciated. O2=870 TPS=.44 IAC=14 BLM=125 Car warm at idle
