I had a HF cheapo that worked for most things, but would not loosen lug nuts
for anything. It was rated at "Max 260 Foot Pounds of torque". After a few
years, I gave it to my son and bought a used Ingersol Rand wrench that was
rated at "450 Foot Pounds". Same thing. I took the IR apart, figuring that
something must be wrong inside, but it was clean as a whistle with no
apparent wear. The only thing I can figure out is that I have too much hose
on my shop setup. Either wrench was fine for tightening lug nuts up, but
neither would loosen them. I always have to use a breaker bar. I was
really surprised that the IR wouldn't work better.

One thing that people miss is the fact that many 1/2" impacts call
for a 1/2" hose. That and the standard quick coupling used is just
like adding a flow control. In the average situation with 3/8" hose
and quick couplings you'll have to run a higher pressure than the gun
is rated for just to get the rated pressure at the gun when it's
running.
