Hi,

I think this is correct but I just wanted to verify :)

Yup, I think it is around 5psi that it "turns on".

Reallly??? Wow... I thought it was the minute the car transitioned into boost.

I ask because sometimes I drive around and am not into boost yet but I see my AFR is 11ish. Now I know that's non adjustable.

Something's not right then. Is this a wideband or narrow band?

Wideband....

Example: I will step on the petal but not all the way down. The boost gauge reads something a little below 0Hg however, the wideband reads 11.5ish. This only happens sometimes. I also noticed that at times I will get a momentary lean reading. I don't think it's a big deal though because I'm only using partial throttle.

It only adds fuel when in boost. Around 1PSI and up. The PC-Pro takes care of the transition.
