$vbulletin->datastore->fetch(array('customname')) adds 1 extra database call

[kh99]

You can create a plugin using hook init_startup and do this:

$new_datastore_fetch[] = 'customname';

That may still add a query if you have no other products adding to $new_datastore_fetch, but if there are other products using it then they will be combined in to one query (the blog uses it, so if you have that then this won't add a query).
