18ish psi all the way to redline is fine. Just need to make sure you have the fuel and timing to suit.

Higher boost can also work. If your ECU has the capacity, running 22ish PSI down low works well with a taper to 18psi at redline to be safe. Or if you are keen to push it and have the supporting mods, you can pump out 21-22 psi.

Its all about having the other mods to support it though.
