Are you sure the problem is with 'tee' and not the commands before it?
I cannot recreate your problem.  Here is an illustration.

  while sleep 1;do date; done | tee /dev/null

The output of tee will be a tty and the libc stdio library will
normally leave that unbuffered.  The commands before it are seeing a
pipe instead of a tty and would traditionally have buffered output.
