One thing about upgrading the pump is speed. With a 1.5" ram in my TJ, stock pump, PSC big bore box, I could turn pretty quickly in one direction, but then it was a brick wall if I wanted to turn back the other way quickly. I found this out when I went to pull out quickly from a left turning lane back into the straight lane. Gave it gas, steered right, went to steer back left and it wouldn't move. Took about 3 lanes of traffic before enough pressure returned to get it straightened out. Fortunately there was nothing beside me, but the cars that were coming up behind me certainly had to hit the brakes for the WTF moment.
