Full boost at what rpm?

my new setup: (hands dirty as i type this from installing parts of it.)

87tii stock port motor with very good compression... about 35k miles on it.
E6k
MP t-70 (Ind. 2.721” May. 3.582”) with a 1.15 divided p-trim turbine housing.
divided fd manifold spaced to so the hotside will clear the LIM
3" turbo back no cats... might go 4" DP and 3" CB once i see where the WG will sit.
24x12x3 bar and plate fmic
Ported and modded TB
4" CAI (no afm... EMS )

Im looking for any idea of when i should start to see positvie pressure and then when ill get full boost (15psi). In 1st 2nd 3rd and 4th.

1st i figure ill only get 10psi
2nd full 15psi by 4.5k
3rd full boost by 4k
4th full boost by 4k

Does this sound about right? Or do i need to go with a 1.00 divided housing?

jaa
