The lower line does appear to be boost, in PSI (don't know why they don't stick with metric?). Appears to show ~4 psi more boost until the very top end. Almost looks like overboost, but the claim is that effects torque but not HP.
No idea how long it had to learn, I think he'll chime in here soon...
