Hello Forum users,
I have read several posts with great interest about the start of injection (pump settings, etc.), boost pressure, and tuning. With this knowledge, I decided to work on my own van. It's a T3

with a 1.9 AFN engine, and according to the seller, it has been chip-tuned.
So, I connected a laptop with VAG-Com and logged data from groups 3 and 4.
What seems strange to me is the boost pressure! Shouldn't it be going up to 1.8 bar?
Could it be that the issue is related to my modification of channel 3, where I tried to disable the EGR system as much as possible by entering the highest possible value?
Thank you for your contributions

.
Best regards, Frebert.
