lean idle after clutch install

hi guys, i just finished installing my clutch over the weekend and after install i started the car and it has been idling lean 16-17 when warm.
sometimes when im driving and giving light boost the wideband also isnt displaying anything. charge piping seems to all be tight along with exhaust. o2 sensor was never loosened or removed from the downpipe but was unclipped and reclipped.

kinda stumped. anyone have any input?

Is the car tuned? On SD or MAF? If on MAF, it's possible you fixed a leak the car was tuned with. Also, if it's on MAF with the stock intake and/or boost controller, make sure the line from the BCS that is supposed to connect to the intake pipe is connected.
