Replying to FKS forward pressure adjustment

I'm having "issues" with the forward pressure adjustment on my FKS 120s. A little background, they are mounted on an Armada Alpha 1 for a 301 bsl Full Tilt Wallisch Pro. These are replacing an FKS 185 drilled for the same boot in the same spot on the same ski.

The issue I'm having is, I cannot get my boot to fully engage in the binding when I step in. I click into the binding and it engages, but I have to pull the heel piece an extra few degrees to fully engage. Is this a function of my forward pressure not being set properly?

Naturally, the response would be to take them to a shop and have them set by a "professional", but these are things I would like to learn for myself as I like to maintain my own shit!
