My 405 T16 in silly heavy on the steering wheel even though I have PAS running on it.
Are there a big difference between different PAS pumps in how heavy it will be on the steering? Flow / pressure differences?
Maybe the cylinder needs to be bigger?
I've got no clue, but it would be nice to get a 407 / 5008 feeling on the steering wheel instead of un-servoed feel it does have today. It is even stiff when driving along, might it be the servo actually restricts movement during driving due to too little flow compared to the cylinder size?
