Inconsistent Boost

[TSi2NV]

Hi All,

I have a 1.4 TSI (90kw - turbo only) and have notice the boost to be very inconsistent lately,

I have a auto-meter mechanical boost gauge and it would normally read between 8-10psi

Last week it felt a little flat and I noticed the boost to be a little low 5 psi, didn't think much of it,

Car didn't get driven over the weekend the yesterday (Monday) car felt super punchy and low and behold it's running 12-13psi (I wasn't to upset by this as the drive was much more fun)

Today (Tuesday) is running 10psi

Does this sound like a dodgy N75 valve?

Engine is stock with a K&N OEM style air filter and a GFB DVS+ divertor valve

Any advise/trolling is welcome

Could be a faulty MAP sensor
