Overboosted steering with hydroboost setup

[groho]

Having recently used a similar tuffstuff kit to reduce my pump pressure for autocross (was percolating the fluid). I can say it does make a difference. It's an easy change, but my suggestion is don't get so aggressive. There's a pin and spring inside the piston that appears to act as a relief and youre changing the pressure point of the valve by extending or shortening that pin and spring. 800psi is a fairly large drop from 1200psi. You're gonna notice it most at slow speed, idle. Don't be surprised if you make more than one attempt to reach the feel you want.
