Posky 777 FDE

I have updated to the latest FDE service pack but there are a few things I would like to point out. Maybe I'm being a bit harsh as this only freeware. But it seems like the engines have a bit too much thrust in them. I can take a fully loaded 777-200 and get it moving at twenty knots with little or minimal throttle push. Usually it takes something like 40-50% N1 to get the beast rolling but not with this one. Is there something I can change in the aircraft cfg or will I just have to live with it? I understand a 777 has a lot of power behind it but this just seems a bit strange or maybe im not used to it.
