Too much transfer is what causes excessive ski lift. Kinda gotta find your own sweet spot with suspension tuning as every riders position on the boards is a little different as well. Did you loosen of the front shock in the skid some as well? The other option would be a coupling kit for the skidframe. I am likely around that same weight all geared up and my '17 163 LE doesn't seem to transfer too much.
My '16 Axys 163x3 was a trencher and out of control climbing until I shortened the front limiter strap by about one inch. Made it much better, added the skid coupler from Source Innovations and now it is perfect! Easy to adjust on the hill and coupler works great.
