I keep getting about 0.2-0.25 bar underboost starting at 4000 rpm in 3rd gear and I cannot figure out exactly why. I'd like some advice on what the cause is. I hope it's just a flow issue from the intake, but I don't know anyone who can help me test it. I'm hoping someone has the time and is willing to help me out with this. I'm located in The Netherlands. I've posted a table with my boost measurements, maybe someone recognizes the issue in this from experience and can help me out that way.
Thanks for taking the time reading about my issue.
