Rather than running the ramjet on the ground, I think it's also equally likely the improvements were part of the actual Dornier 17 aerial testing.

First I am not trying to make you upset. Wind tunnels are usually on the ground. I am not familiar with the details of this project and it is possible that an engine of this type could have been fitted to a Do-17 I find it unlikely though. The engine would have to be center mounted, and if they got the engine running and tested it anywhere near where it needed to run for the P13 the Do-17 would fall apart. The 17 only goes around 500kph which is one quarter of the proposed operating speed. There is no benefit gained by testing it on a Do-17, at least not that I can see, now on a Me-262 or Ar-234 would have been more practicable.
I don't know of any super or trans sonic wind tunnels anywhere during world war 2.

I am not sure what you are trying to say here. That remarkable high nose up means that the plan is on the verge of stall and that if the pilot brings the nose down any he crashes. Delta wings are intended for use at supersonic speeds.
Looking forward to your details and response.
