I have used feeds to import some nodes with taxonomy term reference.

The source XML is the following one.

<items>
  <item>
    <title>Test 1</title>
    <body>Test body 1</body>
    <term>My_term_foo</term>
    </item>
</items>

First import is OK. I edited <term>My_term_bar</term>, and started importing a second feed. After the second time, the node has both "My_term_foo" and "My_term_bar," but I need only "My_term_bar" from the second import.

Is there any hook_feeds_node_item_presave() I can use to alter the values being imported?

EDIT:

My final code of hook_nodeapi inpired by sel_space:

switch ($op) {
      case 'presave':
        if ($old_node = node_load($node->nid)) {
          $taxonomy = array_diff_assoc((array) $node->taxonomy, (array) $old_node->taxonomy);
          if (!empty($taxonomy)) {
            $node->taxonomy = $taxonomy;
          }
        }
        break;
    }

If data needs to be modified before it is saved use this module : Feeds tamper

For advanced modification use hook_nodeapi in drupal 6 with the insert parameter , with hook_nodeapi load the old node like this :

$old_node = node_load(node->nid);
$node->taxonomy = array_diff($old_node->taxonomy,$node->taxonomy)

So now you are sure that the $node contain only the new value , Hope this will help
