I believe that is correct. It has been a while since I plugged in my bluetooth OBD2 adapter, but I want to say that it runs over 20 PSI at max boost. I'd be interested to know the difference between overboost and regular boost, but really need a passenger to watch the torque app to do that. I dont think staring at my phone for 10 seconds while driving at WOT would be a good idea.
Max boost levels?
How much boost does this turbo make on the diesel? The Torque app on my phone\bluetooth OBD2 adapter shows 22.5 psi at WOT. Seems a little high to me.

On my mechanical boost gauge with the factory tune, 23 psi was the max I would see under heavy acceleration.How much boost does this turbo make on the diesel? The Torque app on my phone\bluetooth OBD2 adapter shows 22.5 psi at WOT. Seems a little high to me.

I have seen over 31 psi during wide open throttle after being tuned!

(where are you guys attaching the mechanical boost gauge? i just got a 2014 with 25k miles few days ago)
Is that with a tune mine is completely stock only seen 16 PSI highest on my scan gauge.

That number sounds right to me. I think 21.5 - 22.5 is the max I've seen on my scangauge and I'm completely stock.

Comparably sized gas engines. Glad I'm wrong though!
Mine makes 28 psi under full throttle. Not sure why the number everyone sees varies so much. It's on a 30psi boost gauge and it will almost pin it every time. This is with the boost gauge plumbed directly into the intake pipe just before the manifold.
Your gauge is wrong, or showing absolute, but 28 PSI is really low if its absolute.
Unless the difference with the manifold is that huge, but I don't think it is.

The gauge came out of another vehicle that also had a scangauge and it was consistently within 1psi of it so I don't see how it would be wrong. It also sits dead on 0 at idle. I guess it's possible it could have been dropped or something when it was removed, but it seems to be working fine.Your gauge is wrong, or showing absolute, but 28 PSI is really low if its absolute.

I followed a write up on here of how someone installed theirs. Post 19 in this thread shows the same location I used for mine. Hose comes off that fitting, goes about 12" to the electronic sender.

Then it must just be that huge of a loss, subtract six or so and that would give you the relative pressure of the manifold, or what the OBD2 would give you.
Do you have the diesel?Is that with a tune mine is completely stock only seen 16 PSI highest on my scan gauge.

There is a write up in the diesel technical section. I don't know how to link the write up, you can search for it.(where are you guys attaching the mechanical boost gauge? i just got a 2014 with 25k miles few days ago)

I posted the link to that write up a few posts above.
