I just installed a new Turn One power steering restrictor fitting in my stock LS1 pump. This fitting brings the LS1 pump back down to the pressure of the stock Nissan unit. I can’t say enough about how happy I am with this part. Best $35 I’ve spent on this car in a long time. I can actually feel the road now through the steering wheel.
