Lean tune. Imo
I like to tune on the lean side as well, but under harsh wot the temp spikes and hypers come apart.
Maybe you broke part of the ring land off, maybe you just pushed a head gasket into oil. Leakdown test is in order. The plugs look lean all around the base Circle and all I see is the fuel additive of the brand feel you use or put in which is reddish orange... but that's just what I see in that grainy pic.
Being 40 PSI down is substantial, would take a number of Cc's introduced to lose that much.
