The pressure difference between on and off is too great for

What's the tank pressure? It should be high enough to mask this
effect.

Is your regulator flowing enough air? Is the delivery hose after the
regulator too long and too narrow? The tank pressure should be about
130psi, the regulator about 90 and the pressure at the tool as close
to that as possible (my workshop plumbing delivers at 110psi and I
have regulators by each bench to avoid this drop).

I notice a slight drop on mine[1] when using a framing nailer and 95mm
nails... even with the regulator screwed down tight there is enough drop
off to make the last couple of shots before the compressor recharges to
mean you might not drive the nail completely.

I do tend to use long hoses though, and have an inline oiler on the
output of the compressor.
