When you get this code and go into limp mode is it meaning a boost leak?

Some good information here:


30FF Exhaust fume turbocharger low side
EXPLANATION: ECU boost under ECU target
FIX: Often caused by boost leaks, leaky DVs, broken vacuum lines, etc. Also possibly tuning related. If using a TMAP tune (SSTT/JB+) it may be a sign you need to reduce your boost level, or perform the solenoid bypass.
