I tried reading as much as i could about this 17536 problem but i still have a question.

Since i changed my dv and all my hoses and clamps with forge ones i am left with either the MAF or the O2 sensor. A friend of mine said that once the MAF is finished, the car doesn't work ok at all, but my car has moments when it works perfect and then, no boost. Is that a sign towards the O2 sensor or how can you know for sure?

Today i will try and clean my MAF sensor as i have a can of electrical cleaner spray and see if it is any better...

Quick test for the MAF sensor is to unplug it, and see if the car runs better on the default map.

i was under the impression that if you leave the maf unplugged, the car won't work...stupid me.

So i just went for a run with the maff unplugged and the problem is still there. It feels like i have a N/A car, no boost, power whatsoever. When i started the car another light appeared on my dash, besides the CEL which was already on. Furthermore the car showed signs of rough idle and after i was slowing down, the engine died...

So i guess no point in cleaning the maf now.

The car has only 73k miles and has a BMC air filter for 7k miles. No other mods.

Any advice will be good.

I presume you have automotive electricians in Romania (like garages, but they only work with the electrical systems). If so, ask one of them to check the O2 sensor by reading its voltage directly.
