Review on ECCPP 20 1039 Steering Assist Wrangler by Joshua Garris

I don't know what's wrong with this power steering pump but it is defective. It works great when the engine is running at low revs but with more resistance than the original pump, but for some reason it is difficult to control when the engine revs are increased. Are there times when I'm driving a 4x4 at low speed and need a little boost so I pick up the revs and suddenly I'm having a hard time turning? There are also moments when I climb onto the ramp and overtake the trailer and I can't steer the car into the next lane? This pump is weird and I don't understand why the oil supply is different in different areas, well why it's harder at high speeds than low.
