I’m new to this and I have an 08 wrx the guy I got the car off of had a vf52 turbo pro tuned to 18 psi but I’ve been experiencing what I think is boost creep and was wondering where a good starting point on diagnosing it would be?

When I go about half throttle my wastegate drops to 0 is that normal??

The owner before me obviously did some adjusting of the actuator arm because I found out they had the T hoses backwards, broken bolts on the heat shield, and it's just obvious they were in there at some point trying to raise the boost, or had a "sports car" mechanic that was lost on Subarus. So...
