Steering effort for manual 16:1 - should it be this high?

66fs is correct. This is why I converted to a Firm Feel Stage 3 box and a 850 PSI Saginaw pump. No more slow ratio for me (24:1) and a firm steering feel with just enough assist at slow speed to drive the car at neighbor hood speeds and back out of my garage. Only regret is not going Borgensen box for a faster ratio but I'm not changing now.
