I "think" I noticed a difference on mine... I did a reman'd pump at the same time so its impossible to say which one really woke things up. I still don't have the pressure I would like at idle and standing still, but anything above idle and it moves nicely.

The switch to neutral and a bit of gas is not too bad most of the time, typically I'm in the middle of a 12 point turn when this is a problem anyway.

Still I might be trying a new pump in the near future (debating between some led rock lights and a pump)

You noticed that much out of 5HP? My K&N was supposed to do 12-15HP and I barely noticed that. Maybe you were lower than 60 before?

Hard to say as a normal dyno would not register with my truck and it is too large for the go-cart dynos...:-\
