Oil Pressure Help

[lqdchkn]

I installed my Defi oil pressure sender in the location of the stock idiot light. All is fine except when crusing at about 70-75ish in 5th gear, the gauge does this weird fluttery thing between 4 and 4.5bar. At all other times the gauge reads normally.

I'm hoping that this is just a location issue with light load conditions.

Anyone have any ideas?
