I have a DTB setup with DBW on the SC TB. Between the Turbo intercooler outlet and the SC TB inlet I don't see any vac, after the SC TB I might see like 0.5 psi for maybe 0.3 seconds or so. Why do you ask?

I am running a Gen 2.

(SS is the best high Res I could find, from 20%-100%. I found a low res 0-100%, but there are only 3 samples around the dip, it looks similar in magnitude and shape)

 

Curiosity actually.
I was reviewing some of my logs, and noticed that my turbo always iseems to be able to contribute to boost immediately on throttle application.
Not much initially, but something. This doesn't feel right, because my current turbo is not exactly great and I figured it should take a measurable amount of time to contribute.

I then wondered about your setup, but it makes sense that the turbo would not represent much if any restriction to your supercharger.

 

Dori is back from the body work, and she looks fantastic. The car is nearly done, a couple of detail-ish clean-up things to do.
