Replying to Din and forward pressure... the same????

okay, so i am looking to crank up my dins a little. i looked at the chart that was posted a little while ago, and right now i am at about a 6 din, and i should be at an 8 if i say i am a class lll skier. i am 6'1'' and 155 lbs. so this is about where i should be at. i have never pre-released at 6, but i will be trying some bigger stuff this year, so i think i will need them to be higher.

anyway, my question is what all do i need to adjust to make them right. i know to adjust the din by using the screws on the toe and heel pieces, but is there anything else i have to do? i have heard of people talking about adjusting forward pressure, is this the same as the din setting or is it different?

also, i have salomon s912ti bindings, if anyone knows what i need to adjust on these that would be great.

thanks in advance for the help.
