Question spark break up? or what?

I got my M2 large SMIC on so i turned the boost and fuel up.

I'm running 12.5 psi.

It seems that in higher Rpms 7000-8000 the car is getting spark cut just like a very very very little bit. its not as smooth up there as it should be. I thought that i wasn't getting enough fuel up there so i richend it up even more with the PIM volt it didn't make any differnce

I dont think that I am running too much boost to need to upgrade the ignition yet.

Am i wrong?

Or is there something else that it could be?

i have searched but i couldn't find anything that helped me any links or info would be helpful.

my mods

DP, MP, CB, apexi intake, racing beat spark plug wires, powerFC, M2 large smic, light weight pullies.

Try replacing the plugs then throw it on a dyno.
