Big turbo problems (Focus ST)

So in the process of e-tuning the ST with PD Tuning, I noticed that the car was beginning to struggle in the top end and it sounded like there was a problem with the turbo... This problem lead to the discovery of a continuously reoccurring issue that has plagued this turbo kit since the very beginning. I was tired of dealing with this same problem so I took matters into my own hands.
