P0234 fix?

Recently cracked a cooler, fried FICM & bad injector. Had all fixed inc. an EGR block off. So Im assuming the ECM's been re-flashed. I have the CEL which I expected. As soon as I get on the throttle, or go up hill, I get the P0234, Turbo Overboost code. I get the wrench light & no power AT ALL.

From what Ive been reading the code is because of the new flash. Is this correct & what is everyone doing to correct it?
