My jb4 app is not labeled menu 10 11 or 12. Could you tell me the name of these menus?

Really don't think I need to change anything, just like knowing everything that can be adjusted

I lowered menu 10 and menu 12 automatically lowered itsself.. so the way i see it is menu 10 affects menu 12?... i know menu 12 also automatically adjust itself?.. i lowered 10 to 900 because my wastagates are rattling pretty bad and menu 12 lowered automatically to about 1800 RPM

but how to choose the good setting ?
So 0% closed and 100% open are the same thing......

Setting menu 10 to larger values closes the waste gates -- with 100 (5k rpm) being the most closed position possible without them being engaged. Since "closing" the waste gates is also how you engage them, maximizing this number means you are getting the maximum response from the turbos when the DME requests boost. In other words, the more open they are the farther they have to move to engage and the longer it takes (10ths of a second) to start getting boost when the DME asks for it.

Basically, this delay in engaging the turbos causes 'lag', which is why this used to be called lagfix. On the other hand, if the waste gates get worn, you have to open them more and more to keep them from rattling.

For menu 12, you are adjusting (roughly speaking) the proportion of exhaust energy that you are using for turbo boost at low throttle. When you set the value too high, you are running the turbos when you don't need them, which is why you get the overboost. You could say that the overboost (5 psi at low throttle) means super rapid response at low throttle, but the control system of the engine clearly doesn't like it and you get oscillation if you do this. In bad cases, you'll notice that boost stays on even when you lift the pedal a bit and the car feels like it might not slow down for a brief period.

Menu 11 is a simple mid-boost gas pedal sensitivity, as Terry explained in #10th post. Hope this helps.
