Lower MAP Sensor Nut Size

Does anyone know the lower MAP Sensor Nut Size?
It seems like everything on the car is a 10mm, the MAP Sensor nut on the manifold is.

Well I'm looking to clean my lower MAP since every time it rains/taking it through the car wash, my boost will mess up. Revs up by itself, by barely putting any pressure on the gas pedal, I'll randomly his like 5-10psi.

The bottom MAP nut on my car is a 7mm. Does this sound correct?
My thought is, when the dealership installed the 3.5 Bar, they lost the 10mm and put a 7mm on.
Since the nut is small, it gets wet inside (the nut looks a little rusted as well). So since the only time I get these boost issues is when it gets wet, could it be because of the 7mm nut that's supposed to be a 10mm?

Thanks
