It looks like you 02 isnt functioning properly, other than that it looks like you have some knock in the 3700-4900 range and a little at 5900 and 6500. I would figure out what's wrong with the O2 and get an safc so you can add some fuel in those areas with knock.

is that why i only get 200 miles a tank?

more then likely...

your car would be running rich if the 02 sensor is bad

O2 sensor is supposed to be in the upper 80's to low 90's isnt it? (Im not a 2G'er)

Actually your timing looks okay for the most part. If youre really getting 21 degrees total at 7000 rpms then I would say turn the boost up. (Depends on what your base/mechanical timing is set at how your logger is configured.) A good rule of thumb is at least 15 degrees total timing at the top of the pull.

looks like you have some dips in timing. this would be knock most likely. If you have the ability to add fuel in those RPM ranges then that would be a good idea to try.

If the O2 sensor is shot id replace that first tho before you waste too much more of your time.

I would advise not to turn the boost up just yet until you figure out what's up with your 02 sensor. i suspect it's faulty since i highly doubt you'd be getting all that timing advance if you were really getting that much fuel as the 02 sensor is indicating...

try pulling out your 02 sensor, cleaning it (spraying it with brake cleaner works great) and putting it back in and see if that helps, if not, then i would buy another one or borrow one to test it out.

Replacing the O2 sensor will not change his WOT tune. At WOT the ECU doesn't care about O2 sensor voltage. There will be no change in timing by replacing the O2 sensor at WOT.

I would, however, advise that you replace the O2, just to save your self a crapload of gas. Other than that, you can turn up the boost if you want.
