GIAC Stage 1 = Dinan Stage 2 ? Any dynos or boost graphs ?

How do the 2 tunes compare in regards to power and maximum boost ? Are they very similar ?

The dynos I've seen showed similar gains to 5500 rpm, and above that GIAC S1 had a little more. Dinan says the Stage 2 raises boost from 8.8 to 13.2 psi. That's all I know, hope it helps.
