Not sure if anyone is reading this, hopefully someone can help me at some stage.

So today I unplugged the vacuum pipe from EGR and blanked it.

Car definitely drives better until 2-3k with good pull and without hesitation.

I tried to push on 3rd gear above 3k and looks like lack of boost. Maybe there is a leak somewhere or egr is always open.

Not sure where to look. My MPG dropped a lot

If someone has an idea feel free to comment.

So far I've changed MAF for Bosh one and cleaned MAP ( which made slightly better - maybe is broken?) how to check in INPA ?

Anything else I need to check?

Unplugging EGR made big difference below 3k.
