How many layers has the hose got?
You need to take it off and have a look, if it's not a good quality hose (even if it's new) it will collapse under acceleration as the suction force will draw it together, which also may put extra stress on the filter.
You have to be careful when buying hoses for these kind of turbos, i did a bit of digging when i fiitted a T4 and there are loads of dodgy thin hoses that will collapse.
