Flow Gauge Bouncing WOT

[johntotah94]

Hi Aquamist,

I've noticed that my flow gauge doesn't stay solid and steady, but instead bounces around during wide open throttle. (And actually all occasions). Any suggestions? Do you think thats how it is actually flowing or could it be something with the flow sensor? Ive linked a video describing the situation.

Thanks!

Test/observe the flow by putting in a spare nozzle on the windscreen.
This is a new installation?
