Fpr doesn't mean cold start issues only.
Mine used to start fine hot and cold but changed anyhow.
After that it felt so more responsive.
The only way to check for an air leak would be with a smoke test to be a 100%
I've had air leaks and still running on 18 psi boost, come to think of it I got an air leak on the way home from Gatos once and the car went into limp mode.
The ecu might notice after a good drive then goes to base 0,6 bar if I remember rightly.
Have a word with Ashok about Fpr and air leaks even the slightest air leak could cause a nightmare lol
