APR Diverter Valves Orientation

APR Diverter Valves Orientation
Needing to know the correct orientation of the APR Diverter Valves since I do not recall how the oem ones were? Contacted APR since they did not come with any schematics and turns out they do not know either but to put them on the way the oem's came off.
Boost come in on the side and exit the bottom like most or the opposite?

Was finally able to get an answer back today from APR and it was the opposite of what they initially told me. Below is what their final answer back to me regarding their APR Valves.
(You are going to want to flip it. The bottom is going to be your pressure side and it needs to be connected to the long pressure hose that you can't see in the picture.)
Thanks to everyone again for helping out this seemed to be an easy install and turns out the orientation I had previously installed was wrong.

The "in" part should connect to the inlet. The out should be connected to the smaller pipe that recirculates the air back to the intercooler.

And that is the way I installed them but they are saying it needs to be opposite position than the oem.. Even APR said it needed to be flipped.

Was able to disconnect the rear hose with having to take the intercooler off. This is the way it is supposed to be according to APR.

How was the engine operation with them installed the other way?

When I had them on the same orientation at the factory one I kept getting what sounded like a turbo surge. I just came back from switching them to APR’s recommendation and it sounds better and seems a lot smoother imo..
I reached out to a few on rennlist before I started this thread and they had theirs the same way I have mine now with no issues. Since they did come from APR and they sell them they should know best and also do88 also has them setup this way too if you research their inlets online..

Now I'm scratching my head. I don't really have issues but I'm sure I did it the way as the member above illustrated.
Does anyone know what PSI the spring inside the diversiter valve is rated for? Wonder if it needs changing out with higher boost.

I actually found it earlier but not able to locate it now.
