Just want to know, apparantly tires lose around 1psi a month according to research. How much PSI do you lose ?

I filled up my tires on a cool evening to 39 rear and 37 front and within 2 weeks already rears are 36 / 36.5 and front 35 /35.5

In my opinion this maybe normal but not from other vehicles I have had. The weather is also warmer again here, so its not the cold temp showing a lower value. Remember I filled at cold.
