I went on a roadtrip recently and noticed that I wasnt push'n as much air. I went from 22lbs to 19-20lbs. Everything looks OK. Any comments what it could be?

 

check your hose clamps could be a small boost leak

 

Need more detail to offer better advice. i.e. when does it happen, what rpm?

Did you break the snorkle clips?

 

It used to peak at 22 psi at appox 3500rpm, anything above that it would stay at 22. I made sure the hoses were tight. It acts just like it did before but less pressure. Snorkal clips?

 

Boost leak test?

I too have recently had this happen
-Temp change minimal
-Zero changes to car except oil change (done by myself)
-Now noticable turbo spool and valve function (stock turbo/stock intake)
-Loss of pressure
