I just bought a used 2011 Fox 32 RLC 150. I was changing the fluids and noticed on the damper it is scribed that it has a Trek tune. What is that, and how is it different?

I have noticed on some used forks the seller talks about a DRCV or Trek tune.

I'm sure it is fine, just a bit different compression or something, I suppose.

Any thoughts would be appreciated.
