BTW I saw the
in the first iteration of your other post... I'm withholding my pwn rant because I also really like the idea of a reliable 5SFTE. Please consider the following:
All of those kits, in addition to a FMU, include some way to either trick the map sensor or a piggy back to control things. I've actually used the product in the second link you gave, great product, worked very well on my turbo Dodge when I upped the boost. The gain feature was really helpful to tune with. However, I had larger injectors and a zener diode which was effectively blinding the stock MAP above about 13psi.
To answer your question, I was asking about injector duty cycle because injectors don't typically like to be run at 100% for long periods of time, here are the first couple hits I got from google:

While upping the fuel pressure will make an injector flow more, it can not increase the size of the injector substantially or very reliably. Stock is around 215cc, there is no way you will get one of those injectors to act like a 350+cc injector for very long, if at all. Don't get me wrong, fuel pressure is a great tool for fine tuning a setup but should generally not be relied upon as your only source of extra fueling for boost.

5SFTE...EMS needed?
I'm really not trying to be an a$$, one thing I really like about this board is the maturity (for the most part
) of the discussions. I'm simply trying to point out that while your approach will work, there are better budget minded setups.
