Could ignition timing have to do with bogging under boost?
I replaced the headgasket yesterday and I haven't adjusted the ignition timing yet, could this be the reason why the engine bogs under full boost?

It kind of studders a bit when fully boosting, like it is hesitating. I didn't have this problem before I removed the head but since I haven't set my ignition timing yet, I was figuring that was the culprit. I also need to check my vacuum hoses because my idle is a bit high and my BOV doesn't open fully under full boost even though it is adjusted to as loose as it gets (I am running 8 psi and it shouldn't be that loose).

I advanced the timing a bit and the problem went away. I got really bad gas mileage with the timing like it was. I would assume that the fuel pressure was too high and most of it went out my tailpipe. I do still have the idle problem. I have two taps in my FPR line: 1 to the wastegate and 1 to the BOV. Is there somewhere else that you guys recommend I connect these? I tried connecting the BOV hose to the vaccum hose on the secondary butterfly dashpot but it didn't open properly. Thanks for the advice though, I was definitely running too rich. I'll pull the spark plugs this weekend and see what they say.
