There are a lot of great minds on this forum and they're all trying to help you. It's a simple request if you want our help, jack up the car or look down the back of the motor and trace your hoses, take a photo, post it. With out seeing it and you admitting you have little experience with these cars we can't say with any certainty what is going on with your car.
In this thread I've seen pcv systems, compressor side capped, and the sounds of a mod that can be done in a parking lot that is divided as to if it's worth doing but does not hurt your car in any way. None of what you've provided this thread helps us help you and no one is going to crawl under their own car to look for a problem they don't have.
I suggest a jack and jack stand or some ramps and thoroughly inspect under your car and any questionable things you see take photos and post them and we'll be glad to help you out. Also, if it is a vta mod they can be done and seen from the top of the engine with the engine cover removed which is held in by the oil cap. But we need more information, I also suggest a good scan tool, many of us use forscan, you can see manifold pressures and get an idea as to if the turbos are working properly. If you don't want the headache then bring it to a reputable shop and have them look it over.
