This will remove the attachment size limit completely for mods and admins, if thats helpful.

In admin/functions Find:

    if ($maxattachsize!=0 and $filesize>$maxattachsize) {
      // too big!
      @unlink($attachment);
      eval("standarderror(\"".gettemplate("error_attachtoobig")."\");");
      exit;
    }

Replace it with:

  if ($maxattachsize!=0 and $filesize>$maxattachsize and $bbuserinfo[usergroupid]!=5 and $bbuserinfo[usergroupid]!=6 and $bbuserinfo[usergroupid]!=7) {
      // too big!
      @unlink($attachment);
      eval("standarderror(\"".gettemplate("error_attachtoobig")."\");");
      exit;
    }
