For size changing, edit the sr3_city.lua
All you need is search for :
elseif HEIGHT_UP_COUNTER == 21 then
player_change_default_size(LOCAL_PLAYER, ##.0, false)
sandboxplus_message(" Increase Player Size ##.0")
## is the size you want (max was 10, so for doubling that, replace ## with 20), save the file and that's all, you are ready to go !
