If plan B is to send the WUR off to BL to be made adjustable then you have nothing to lose by trying to tap it down yourself. I've done this numerous times as high cold start pressure is a very common problem. I've never overshot the target pressure. You just have to be patient and never tap hard. If the area is rusty soak it overnight.

Here is a picture of the gages mounted during a tuning session using a WUR that was made adjustable.
