Hi there.
I have a 1.9tdi sportline with a Stage1 Map and straight pipe, I might be exaggerating or a bit to extra. When I checked vcds the Actual Intake Pressure is less than the Specified and when I checked my friends values with the exact same mods his Actual Intake pressure is the same as the Specified. Is this something to worry about? See link for my values

Re: 1.9tdi Intake Actual Pressure
Most likely a boost leak somewhere, Unless the specified boost is to high for the turbo to reach, But doubt that

Re: 1.9tdi Intake Actual Pressure
Hi Keegan , the actual and specified wont always be spot on as long s it doesn't deviate to much , also you need to run logs while driving the car under full load lets say from 2000 - 4000 rpm then look at the values.Keegan1.9tdi wrote: ↑Thu Oct 14, 2021 8:59 am Hi there.

Re: 1.9tdi Intake Actual Pressure
Hi G-spot, I am busy trying to make me a smoke leak tester to make sure that there isn't any leaks that that the eye can't see. I had a vacuum leak to the turbo actuator but that is fixed.

According to the logs your actual pressure is higher than the specified values. But figures thats the wrong way around.
Check for leaks

Re: 1.9tdi Intake Actual Pressure
you should be able to find it quite easily, It should have some oil residue built up around the leak area
Check the join between the boost pipes and intercooler. A common leaky area
