How to get weight & balance in toolbar

I’d give JD’s mod a try (not sure if it’s compatible with SU5 though):

Update: JDs King Air 350i Improvement Mod Reworked

16.06.2021 New version 1.1 Adjusted the Fligh Dynamics Part of my Mod to account for the changes Asobo made on the King Air with the last SimUpdate. Asobo corrected some major engine logic errors. Aircraft has a good performance now, but still istn´t powerfull enough. So i again gave it a 11% flat thrust boost. Speeds are nearly POH. Asobo made no real flight dynamic changes though, so I again made some changes to lift and drag of the flaps, for better landing behaviour. I also adjusted N1-TQ …

If your changes are not part of the mod you might want to suggest JD to include it. I didn’t check.
