Okay so I have installed a Evil Auto Style Oil Pressure gauge, The sensor is right where all the searches I found on install its right by the oil filter!. and I put it in, The PSI shoots up to 60PSI, is this normal? and it stays there... then when the car is in nutral it starts to fall to 0, but as soon as i go back in to gear it shoots back up to 60 and if i drive it it starts to fall back down slowly, so is this normal or is my car just being stubborn?

 

So I have replaced the sending unit, and it still just goes up to 60PSI but only goes to 0 if the clutch is out... any suggestions guys?
