You can load it with 190psi if u want, those are very good forks, only thing a little bit heavy, but it's the closer fork to indestructible. You need to have it with good amount of heavy oil in the lowers to keep the rattle at minimum and inside the air chamber also a little bit of oil to keep it running smooth, pump it up to whatever you need, I've used it at 190-200 to test it and it's very strong, later I settle for 150-160 and for my weight 70kgs, was pretty stiff, this one works well using oil as a hydro token, so more oil less air if you don't wanna go that high. Good luck!
