Having the most peculiar problem since I got my car back from head gasket swap.
Car is normal in the first few seconds of getting on throttle hitting 20~21 psi, after a few seconds it drops to 11~10psi. Drive normally then get on it again and the same thing happens. If I'm always on the gas without normal driving, it's always 11-9 psi. Does not seem to be affected by rpm. As long as it takes a break, it'll go back to full boost.
It feels like as if something heated up during higher boost causing lost in boost pressure and goes back to normal when it cools. Checked all clamps, they're tight... Any clue?
