) since they usually leave them unmolested (no screwing with settings).

Seems like the tune (and boost pill) is the most important upgrade and that catback, filters, TP, UICP, etc aren't adding much after that. What is next mod that would add significant HP/TQ? IC upgrade? Full turbo-back (that replaces O2 housing)? or ??

OK. Several good responses. THANKS!
Now, I'd like to change the questions slightly. I had asked what would it take to make 300/300 on an X. The variation would be, what would it take to make 300/300 at the lowest boost level possible on 91?
IOW, instead of turning up the boost for more power, how could an X make 300/300 at less boost, say, 18 psi?

Got a question too (on 91 oct):
Based on GST dyno sheets, average peak from a tuned all-stock X is around 285whp (w/ pill). If you add a drop-in filter (say a Cosworth) & a 3" dual catback (like Magnaflow) on top of a custom tune, how much more peak whp will it add? Would it be close to 300whp?
I'm hearing a lot of people say that a panel filter does not yield any gains after a custom tune, but if you pair that with a catback, would the filter actually help extract more hp?
