I noticed that a psi-blast report only considers new hits if the 0.0 < E-value < 0.01 (?). Is there any possibility to change these parameters ? especially the 0.0 limit, cause large query sequences with 60% identity might still give an e value of 0.0, thereby causing me to miss them completely by
You can set the -h value ($blaster->h()) to adjust the inclusion threshold for refining the scoring matrix. However, it only takes expect values - not identity/length - and the expect value can't go below zero.

I think he meant that evalues that are exactly zero get excluded, as
the threshold is tested with a "lower than" (`<') instead of an "lower
or equal than" (`<=').
