re-loaded known good map, sudden issues

[fkingsuv]

Yesterday i hooked up to my vems box for the first time in months. 
i opened a known good msq,  and burned to ecu.

no unusual errors, but suddenly now every time the ecu sees over 100kpa, i feel a giant stutter.  logs show DC cutting out.  idle/cruise is way rich aswell
What have i done?
I have tried numerous other know good maps, but they all respond the same.

heres a screen cap of the log:


Im currently running MegaTune 2.25 p3 with VEMS v1.0.78
Any help would be greatly appreciated

Your fuel cut is coming in, it must be set to just above 100kpa.
