Point taken. I have a 60 gallon 2-cylinder DeVilbiss in the garage and a
pair of 3/8" lines in series, at about 100# pressure. Sounds like a #1
without the torque stick should be pretty close to 80#, but I'll check.
Thanks for the advice!!

I've actually checked my impact gun against the torque wrench on #1
position. You do have variables, though, I was at the VW dealer at the time
I checked it, they had two Campbell-Hausfield rotary compressors, and 1/2"
pipe run to the hose reels in each tech's bay. The hose reels used 3/8" air
hose, and those compressors would keep the pressure at the reels (we had a
gauge on each manifold pipe that ran down the wall along the bays on each
side of the shop) at about 120#. At that pressure in #1 position, it would
do 90 ft./lbs. At the tuner shop I went to following the VW dealer, they had
a single off-brand piston compressor, 60 gallon tank, and 3/8" pipe to the
quick disconnect, with 90lbs. available at the hose. I could only do 70
ft./lbs. in #1 position. So piping size, tank and compressor capacity
definitely make a difference.
