Analog stick range/limit issue on Trimui Smart Pro

Trimui Smart Pro devices are having an issue where if you push the analog sticks forward with a bit of force, the system registers it as a very slight input.

In Crash Bandicoot: Warped, for example, the character walks very slowly even when the stick is being pushed to its physical limit.

Has anyone managed to calibrate this?

I was able to fix it in RetroArch by increasing the sensitivity, but that doesn’t solve the problem for PPSSPP or PortMaster games.
