Hi, I am currently having a problem with the turbo getting up to full pressure. While I have been searching I have seen a lot of turbo problems where when they fail, they over boost and send the car into limp home mode. Mine has the opposite problem, it struggles to get to full boost but doesn't flag any errors in the ECU.

The link below shows the VCDS graphs of my boost compared to a friend with the same engine in a skoda octavia VRS.

Sorry, I cant properly attach the image because I am new here, if someone could attach it to their reply I would be very grateful.

RPM is on the bottom and boost on the left. As you can see my leon doesn't hit full boost (2500) until 3200 RPM while my friends (and I expect everyone else's) has full boost by around 1850 RMP. Past 3200 it stay fine at full boost.

Has anyone else had this problem or can make any suggestions?
