implementation of pscbo_stats package results in worse performance

Hi Community

I am trying to implement the recommended pscbo_stats package shown on pscbo_stats - Improving Statistics in Oracle RDBMS for PeopleSoft Enterprise ( Doc ID 1322888.1 ). I've loaded it into a copy of our production HCM 9.2 database with Oracle 11.2.0.4 on Exadata. So far most queries are slower. For example the TL_TIMEADMIN process which for us currently takes about 1.5 hrs. After setting up the pscbo_stats package, the job now takes 6 hours.  I have followed the documentation closely and did not have any problems with installation.

I am seeking to find out what options exist for troubleshooting? We have tried modifying the STATS value to 'Y' within SYSADM.PSCBO_STATS_CONTROL for related tables as suggested in the FAQ, but it did not yield any significant results.
