Yes , that what I was looking for .
Difference number looks good but your numbers are very low on boost pressure , never seen this much low , Possible someone was messing with VNT Actuator or closing point of turbo exhaust side and that could make problem what you experiencing .
Numbers needs to be close what I have in my post .
Do you have Vacuum pump ?
If you do , can you please do this , Put Vacuum pump on VNT Turbo Actuator, apply vacuum very slowly and tell me when rod start moving what number you have on gauge and when stop?
They need to be when start moving 4-5 when stop 17-19. This can be difficult to see it at first time so may do it few times , you need to catch it soon as that rod move .
I did that as well. I tested it about 5 times. Each time the rod started to move at 4-5 and would stop at 16-17. The shaft moves smoothly and I could not feel any vibration or sticking when it was moving. The last time I looked at the turbocharger blades they looked good and there was no play in either direction of the shaft. From a standing start and putting the fuel peddle to the floor, the car wants to put you in the back seat. It shifts smoothly with no hiccups.
Could there be a drop in system vacuum when the engine is changing from a slight descent to an incline? Without going through the trouble of installing a vacuum gauge, can I get a real time vacuum reading using the VCDS? Again, this stumble doesn’t happen all the time just once in a while after an all-day drive in hot weather.
