Rockshox Deluxe Select+ IFP pressure, which damper do I have?

I have a 2021 Deluxe Select+ shock and i'm gathering tools for the damper service. The RS manual lists a few IFP pressures, but i'm not sure what damper I have:

Does anyone know what damper this shock has and which IFP pressure do I need to use? My pump goes up to 360psi so i'm hoping it's 350.

Your picture shows an 2019+ RT. So the correct pressure would be 420psi.

The RT stands for Rebound Threshold. You can identify your RS Shocks by their external settings.

For example, if your climb switch would have 3 positions (open, trail, closed) if would be an RT3.

Dangit!

I have the same shock as on the pic, it came on a 2021 Radon Slide Trail 8.0, two position switch, no compression adjustment.

BTW my shock makes the same noise, i've seen a few vids of it online.

Is it really just the negative chamber equalising? Seems weird. It's been like this since new. I can also feel a bit of a difference in the amount of force needed to compress the shock. It's easier, then gets harder, then I reach the part where it makes the noise, then it gets harder again. Happens at 20% sag. I can't hear it with no air in the shock.

Yes, just equalizing.

You are compressing the air (gets harder), at 20% the air chambers are open to each other (gets easier or 'free" momentarily), after 20% they are sealed again and you are compressing the air (gets harder).

The fact that there is a dead spot when they equalize is why some shocks such as Manitou have a fixed negative chamber that does not adjust based on the positive chamber. No dead spot in the support.
