Yesterday I fitted an induction kit to my VXR which I've owned for 3 days, it's the direct to turbo feed kit using Roose silicone pipes and a cone filter. The filter seems a little on the small side to me but to be fair it does fill most of the available space and I collected it from the previous owner who had it fitted previously.
The issue is under heavy boost always around the 4500rpm area it now seems to choke the engine as if it isn't getting enough air through and I lose boost and it pulls more like a 2.0 N/A than a 2.0T. I should mention that prior to fitting the kit there was no issue whatsoever and it pulled right to the redline like a lunatic.
My question is could it be that the filter itself is too small and so restricting the air flow under heavy load or could it be the standard pipes on the right side of the engine bay sucking themselves flat and choking it off?
It could be anything else as well I guess but these are all I can think of right now.

Thanks in advance.
