DRW / BUICK 91mm exhaust back pressure reading

I finally got around to measuring the exhaust back pressure with the new B/W Airwerks S510/91mm turbocharger setup. Not the most scientific method. Intake boost pressure was 27-28 psi. The amount of exhaust back pressure was 23-24 psi.
.82-.88:1 exhaust back pressure to intake boost pressure. Major crossover has been achieved!

@YOUNGVICK313 The local track I test on goes sour after the concrete launch pad. I actually have to pull boost out for the 1-2 shift, and then slowly ramp it back in. If you look at the vids where the car is on a 1/4 track, I don't have the same problem.

If you look closely at the track in the vid, you can see where the track condition changes just as I'm shifting to 2nd gear.

What are using for boost control ams 1000?

[DonW21G]

I don't have anymore at the moment. I should have more in a month or so. I'm working on the launch tuneup. I've got to get her out of the hole a little quicker.
