Yes I have put the chemical metal on the wastegate arm but it is not a very good surface, not sure if it will hold, TBH. But logically speaking it must be the small amount of flex in the wastegate actuator bracket causing the issue, because the difference in turbo pressure even at idle was very noticeable. I am just surprised that such a small amount of movement could cause that much reduction in pressure. I also have to experiment with removing the shims from the wastegate actuator's stud.
