I know it's simply unplug and plug the hose but I am not sure how many vacuum lines are there..
Also I read that people saying don't bother those vacuum lines behind the engine or wastegate and only do those ones on top of the engine, is it true?
Any silicone hose from SCA will do? May I ask what size should I get?
Thanks.
And wish you all the best and solved the problem soon Harms.

You want 3.5mm vacuum line, this is a local source for the braided stuff:

I bought 3 metres
I couldn't find a good source local for 3.5mm line so I went FCP euro when I was buying a bunch of other stuff:

Its hard to find 3.5mm smooth hose locally so a lot of people go 4mm instead. I can't say I agree with this because they don't stay on the nipples as tightly and the larger diameter makes them not fit in the hose clips properly. Just do it properly and buy the correct diameter.
Ideally replace ALL lines, the turbo wastegate braided lines are the most difficult but they are the ones subjected to the most heat. I did notice better boost response after changing out my lines. Make sure you slice the lines with a scalpel because the rubber tends to stick to the nipples. You could easily break the plastic nipples trying to get the rubber lines off.
