Turbo hosing w/higher turbo boost?

[Audial@aol.com]

I received a message recently from someone about the TAP vs. IA chip mod that
indicated I should probably worry about the longevity of the hoses and
intercooler should I choose to increase boost on my car.  I inspected
everything tonight and the hoses seem strong.  Should I preemptively replace
the hoses before I increase the boost?  Also, the intercooler construction
doesn't look very robust.  Has anyone encountered intercooler failure with
increased boost?

Finally, one more question:

The IA mod includes the wastegate spring.  Does the TAP or do you have to
get/make/beg/steal your own?  My impression with recent posts is that the IA
is complete while the TAP isn't in this aspect.

Thanks,
