I have set my GM pump pressure many times, I beleive the problem is dual, a constant pressure pump and a 2 1/2 turn lock to lock rack. The manual rack's are 4 turn LTL. My steering is still very responsive (touchy). I would like to know if the Flaming river power rack kit is any better with a variable pressure pump, I beleive they say pressure drops with increased RPM. Anyone try Flaming River power rack KIT?
