Replying to Full Tilt tightness

I got a new pair of drop kicks at the start of last season. They have over 100 days for sure. The boot is in decent condition but the liners are most likely packed out. I bought the claims a few weeks ago and after skiing in the I noticed that they are much tighter to my feet than my drop kicks. Like I only need to have the buckle a few clicks in while on my drop kicks they are maxed out and still not even close to that tight. I also have the power strap at tight as I can get it. I noticed that I actually ski jumps better in the claims. I land tricks better than with the drop kicks. Is there anyway to get the drop kicks buckles tighter. I assume it is a combo of the liners packing out and the cables streching but is their anything I can do? Like has anyone cut the cables or something like that?
