oh good I am not an idiot
I listen to all the people talking about waiting for the utec
to eliminate boost creep, and wondered how it could possibly do that. Same thing happens on eagle talons, but there it raises boost from 10 to about 13 psi, still safe and nowhere near fuel cut.

The only way to get rid of creep is to port the wastegate.
unless you are planning to use the utec, to actually tune the car
based on the 20psi you will be running.

another thing to consider before going for a tbe
when you see manufactures claims of hp increase
most of it is due to the increase in boost.

for example my old fwd eagle talon dynos at 145 whp stock (10psi) after TBE (with cat) 170whp (13 psi)
after i had my turbo ported, I tried setting the boost back to stock(10psi) with the TBE, dynoed at 151. Then same day turned the boost up to 13psi power back up to 170whp

So basically the TBE gave minimal gains on its own
all the claims from the aftermarket shops were kinda
misleading. Taking the credit from boost creep
in their hp increase claims.

I know these are totally different cars
but when I see a company claiming their exhaust makes an extra 27 whp for the sti, the first thing that i think is, oh 20 hp for the extra boost, 7 for the exhaust
