Question for PeopleSoft DBAs out there

We've a NVS RPTBOOK that keeps going out to lunch on PS_LEDGER with a Cartesian Join. We're using PeopleSoft Financials 9 and I've tried to tweak the performance any way I can and cannot get this query to come back.  

The NVS RptBooks use templates where you specify the criteria so the underlying query can't be rewritten. We're running CHOOSE with Oracle 10.2.0.3.  

Anyone come across anything like this before?  

Here's the query:  

SELECT l1.tree_node_num, l2.tree_node_num, SUM (a.posted_total_amt)

    FROM PS_LEDGER a, PSTREESELECT10 l1, PSTREESELECT10 l2, PSTREESELECT05 l

   WHERE a.ledger = 'ACTUALS'

     AND a.fiscal_year = 2006

     AND a.accounting_period BETWEEN 1 AND 12

     AND l1.selector_num = 14422

     AND a.deptid >= l1.range_from_10

     AND a.deptid <= l1.range_to_10

     AND ( l1.tree_node_num BETWEEN 1996093750 AND 1997802733

          OR l1.tree_node_num BETWEEN 1998046875 AND 1999023436

          OR l1.tree_node_num BETWEEN 1999267577 AND 1999389646

          OR l1.tree_node_num BETWEEN 1999450682 AND 1999511717

)

     AND l2.selector_num = 13780

     AND a.ACCOUNT >= l2.range_from_10

     AND a.ACCOUNT <= l2.range_to_10

     AND ( l2.tree_node_num BETWEEN 1687500000 AND 1734374999

          OR l2.tree_node_num BETWEEN 1750000000 AND 1874999999

)

     AND l.selector_num = 13782

     AND a.business_unit = l.range_from_05

     AND l.tree_node_num BETWEEN 1750000000 AND 2000000000

     AND a.currency_cd = 'USD'

     AND a.statistics_code = ' '

GROUP BY l1.tree_node_num, l2.tree_node_num
