Steinhilper saying change the RPM

Completely out of context. Silliness like this adds nothing to the discussion and simply an attack.
You change rpm to achieve a given performance. For example, best climb rate is acieved at a specific rpm and manifold pressure.
Steinhilper is changing rpm and manifold pressure in this case to an overboost or combat power rating.
Because his propeller is not constant speed, he must coarsen the pitch to maintain that rpm.
Basic propeller operation....
Only difference is a Constant Speed propeller coarsen's the pitch automatically perfectly timed to the airload.
The German pilots had to do it manually.

•When increasing power, increase the r.p.m. first, and then the manifold pressure.
• When decreasing power, decrease the manifold pressure first, and then decrease the r.p.m.

Steinhilper and Crumpp are saying the exact same thing.
