I weigh about 235 with gear, pack, etc.. and am running about 145 lbs in the main tube and 200 or so in the Evol chamber on the X shock with all the low speed, high speed and compression settings a little faster/stiffer than center (center/neutral being around 12 clicks, I think), and the front shock around 60 lbs. I have found that you need to check the main tube pressure at the beginning of every ride and often fill it as temp. changes seem to change air pressure a lot. You may want to up your compression setting since you weigh more, but it should not be much more and maybe drop the HS rebound a bit so the rear is not popping up too quick. Hope that helps.
