Hesitation WOT

[Capinoy123]

So This year my car does not want to run under WOT. Built 2.0 liter BC 280 cams, ECM Link V2. (I'll try to take a log of my WOT tonight on my way home from class.) Bosch 044 Fuel pump -8 fuel feed, -6 return, aeromotive fuel pressure regulator. 1650 blue maxx injectors. Magnus Intake manifold 3" Gm maf so on and so forth. Just trying to get ideas. I use to run 25 PSI all day long but it starts to hesitate as soon as it hits full boost or shortly after. So i thought ignition issues? So i turn the boost as low as it would go. 12 PSI and same thing still hesitates under WOT. I'm running about 11.0-12.0 A/F at WOT. Any suggestions would help thanks!
