Isn't there also some conversion you have to do for the PCV when you do the LS1/LS6 swap?

The only thing different when switching to the LS6 is deleting the EGR....the PCV stays the same. Booster is hooked up. I didnt change the TB gasket but if that were leaking wouldnt i hear it? Especially it im idling at almost 2k RPM's
