Thanks again
I may also go as low as the 18psi and see what I think.
Have gone 21psi front and 22psi back. Drove over to a race exhaust place in Warrnambool Victoria, about 400 km round trip and it did feel better.
Less jumpy on the rough undulating bitumen and it felt more responsive through the steering (read novice driver).
Will keep experimenting.
Thanks all
