I use a plugin on my forum to only send so much.

hook location - external_query:

PHP Code:

unset($vbulletin->GPC['fulldesc']);
$vbulletin->options['threadpreview'] = 150;
$hook_query_fields .= ",LEFT(post.pagetext,300) AS message"; 


Modify to however you want.

If I recall, you need to wait to see it take effect because of the cache lifespan.
