Hesitation and cutting out at WOT

[mitsuman18]

It just started happening after my last time at the track. I used some 110 octane. It started right after I put the gas in. Let the tank run almost empty then filled it up with 93 and some lucas fuel system treatment. Changed my plugs (which looked fried) to some BPR7ES's. The car has not changed at all. It still feels like a big loss of horsepower and it still misses like plugs. I'm running 16 psi. Plugs are gapped at .030. Also have some brand new 8.5 mm wires. Any ideas?

try to gap them at .28 that should help

ok I'll try that. It is acting a little better. Hopefully the gapping will help. It might just need to be totally worked out of my system.
