Underdrive pulleys will help a little but the shims are far more effective. The limitation is how much the pump can be underdriven before losing PS at low RPMs which is when you need more power assist. Also risk damaging the pump. The pump is pumping air when you lose PS assist which will cause pump damage.
The shims give more assist when you need it, less when you don’t. Only costs $20.
