Depends on your driving style, traffic, temperature, etc..
It is smart system, will keep engine running in a cold weather, hot weather, in a rain, in reverse, uphill, when engine is not hot enough, voltage on the battery is not high, probably in some other circumstances.
Also you do not need to worry about turbocharger temperature when the engine is off. Giulia has the same turbo cooling system (after-run electric pump which can works up to 10 minutes after engine was off) as 4C and american 1.4 Turbo Multiair.
The 2.0 GME has two completely separate cooling circuits: the high temperature loop feeds the engine block and head, engine oil, low pressure EGR and cabin heater, and the low temperature one cools the intercooler and turbo. The HT circuit has a belt-driven pump, while the LT one has an electric pump. Both loops have electronic bypass valves rather than conventional thermostats.
