White Smoke/Laggy/High EGT's ??

My truck is very smoky down low with no power until about 10psi/2000RPM where it starts to pull hard. Fuel pressure is 14psi from an Airdog 150.
No coolant loss or oil abnormalities. EGT's are high. I can easily go past 1200 driving around town with moderate hills.

I recently did the head gasket on my truck. Brand new head used, surfaced for reassurance. The truck did NOT do this before the head gasket job. I am just trying to figure out what the culprit is here, because smoking people out with white smoke from a red light and the high EGT's is getting old. ANY input would be appreciated.

14 psi is really low for these trucks and I had I issue before With smoke ended up being pump timing but don't know with those high egts.. I would pin time the pump and search the forums

PSI is now at 40. Replaced the spring in the airdog and that didnt change anything.
