Turbo idle after hard use: YES for older turbos with oil-fed bearings. After hard driving: idle 1-2 minutes before shutdown. Oil continues flowing and cooling turbo bearing while idling. Without idle: oil in turbo bearing area bakes onto metal (coking) reducing bearing lubrication over time. Modern turbos with water cooling: less critical but still good practice. Turbo timers hold engine running after key-out — useful for track use. Street driving: usually not critical unless you were driving hard in last mile.
