6.0 Idles great but no rev-up

My 6.0 had codes p0261,264,267,270,273,276,279,281,282,611,677
I start the engine and it idles OK! If i add any throttle, it dies down
and blows out a lot of smoke, which doesn't smell like coolant by the way!!
The smoke is white, but not sure what is going on.
Seeing the P0611 code, I checked the ficm voltage, removing the GPCM plug, coolant reservoir, and the cover plate on the ficm. KOEO=32V.
Should be close to 48V so I ordered BPD upgraded 58V 6 Phase power supply.
After the install, I checked the voltage again and got 57.5 volts.
Truck starts and idles better than ever before, BUT...
I still have no rev up when i add throttle, and the smoke is still there.
Any help, Please???
By the way, I just thought that I forgot to mention that I cleared codes, and P0611 still returns every time, without starting and also getting a p0404 egr performance code.
I had EGR cooler fail before, but not cause me to have no or negative throttle response.

Problem solved. Removed EGR valve today. It was stuck open. I can't believe I overlooked the fact that it could be stuck open! I replaced it and now truck runs great!
