Yes, the Pico WPS can be used with Snap-on scopes to display the data critical to your analysis.
However, the Snap-on scopes do not have a preset for the Pico WPS which means the screen will display volts instead of PSI.
Sorry, I don't have a screen captured from a Snap-on scope.
The screenshot below, from a Pico WPS, shows the exhaust valve opening but the intake valve is not.
Note the scaling for the green waveform is +/- 12.5 psi.
