Is the noise at same speed as the rpms ?

Hope it's nothing serious !

Could be your throttle sticking . If you pull it out and give it a good clean , especially the areas close to the shaft each side . See if that helps.

It looks to me like the outlet is too far around and at too much of an angle to the turbine to work properly ...hence the boost creep . Hope the bigger WG solves that for you.
