Low boost: 4psi-14.7psi
Medium boost: 9psi-20psi
High boost: 16psi-32psi

I do not know which wastegate they are shipping with the kits. Even the lowest boost wastegate is capable of producing the hp results posted earlier though. Max can answer your question better than I can but I hope this helps.
