Hi guys, just a quick one, what sort of boost is your k03s producing at what revs.

Mineis at around 20psi at 4k then drops quite quickly to 11psi for rest of the revs!!

Been having problems with mine. I had same as you hit 20 then drop to 10-11 straight away. Found out my d/v was causing me to lose boost.
Now hits 20psi and either holds it or starts to drop to 16 and stays there. Still think there is a slight problem somewhere. Used to hold 20 strong.
