WOT engine cutting out

[LSTTYPE]

E85 tune. Cutting out at wot. Boost is at 21 to 22 psi. Wide band is e85 specific gauge and says around 7.2 to 7.4 range which is in range if not a little rich. Plugs are ngk ur6 gapped at 28. New old stock coil pack and ignition module new wires etc. went 11.42 last year not cutting out. Any ideas?

Same coil pack and module as last year?

 

[LSTTYPE]

Yes. Just put them on last year when I converted to e85. They are genuine gm nos coil pack and ignition module. I'm gonna check the plugs and probably replace them at a tighter 26 gap. Other than that I might have to invest in a tr6.
