Gauge turning off for a little while?

[Evomoe]

Hi Guys,

I'm a new member of this forum and have just installed my HFS-3 meth/water kit on my evo 9 yesterday.

After burnzy helping me with the installing and tuning, its going great! Am really happy with it.

Just one thing however. When cruising at low rpms(between 2-4max) the gauge seems to shut off, with only the yellow WL LED on. It stays like this for a few seconds then goes back to normal.

I thought it would be a bad power connection but wouldn't the whole gauge shut off? Would it something to do the with the Water level sensor as I do have a twin tank system with baffles inside it.

Any help would be greatly appreciated.
Cheers
Moe
