Yep, I don't know about just an intake and cat back, but if you start to get into different intake manifold or headers, there are definitely additional gains to be made over simply adjusting fueling and spark.
That said, it remains an empirical question -- I should think it's certainly worth exploring with intake, exhaust and anything other than the OEM CAT (i.e., HFC's or TP's).
