8-10psi is differnt on alot of things especially size of turbo and health of engine as well as manifold, dp, etc.

Here's an example of my hp at 10psi.
GT4088
10psi with 3" dp and 2.5" IC piping= 383whp
10psi with 4" dp and 3" IC piping = 410whp

T3/T4B Super V
15psi=283whp

T3/T4B Super V untuned @ 10psi = Weaker than stock (back in 1996 )

see the difference? its not about what boost level but about hp output at that boost pressure.
