did you look at the bin? I just opened it. timing @ WOT @ 8000RPM is 35. I run 29 on mine....
fueling looks fine. I suspect the issue is NOT the tune unless you have been really hammering it with lower quality gas and didn't actually take it to a tuner (basically doing everything wrong.)
to me sounds like a blown head gasket which may not necessarily be the tune.
what is base timing, what is your afrs, what do your spark plugs look like?
