No Boost below 2200 , Blue-ish haze from exhaust in 1st or Neutral above 1800

[97XLT7.3]

I am having a problem with my truck and it is driving me nuts

Here is the Info on the Truck
Year : 97
Model : F-350 Cab & Chassis 4x4
Engine : 7.3
Trans : Manual
Intake : Stock
Exhaust : Stock
Turbo : Stock
Injectors : Stock
Miles : 204,100
Chip : No

Ok here is the issue. When accelerating in 1st Gear (while towing) at any RPM above 1800 i get a Blue-ish light Haze from the Exhaust. It Occasionally does this in 2nd while not towing. When doing Normal Driving , i have no boost pressure until about 2200 RPM at which point it acts like you hit a Nitrous switch , instant power until the yellow line. I do have a Boost Gauge and my figures are as follows (all figures are readings at yellow line) , 1st gear - ~3psi , 2nd - ~4psi , 3rd - ~9 psi , 4th - ~13psi , 5th(pushing to the extreme limit) - ~15psi. As stated , it does not kick in till around 2200 RPM. So today i went out with my Mac Taskmaster and decided to run some Self-Tests.

1. Read Codes
- P0111-49 State Ready

2. Injector Buzz Test
-Pass , no issues

3. KEOR Self Test
- P0476-Exhaust Pressure Control Valve Performance

4. KEOR Cylinder Contribution Test
- P0196-Engine Oil Temperature Sensor Circuit

All test were performed with Engine Coolant Temp Gauge right in the middle of the word Normal and with an Engine Oil Temp of ~155 Degrees Fahrenheit

and here is 2 videos we took , these were done in neutral , haze begins around 18-1900 RPM , loss of power from there till 2600 RPM , the Engine Revs freely from 2600-Yellow Line , Repeated this 3 times with same results
