stolen from a many years old f150forum.com post:It may have been said else where but it is recommended on turbo boosted engines to idle before shutting off to ensure all components stay lubricated.
While this was true of turbo's of the past, it is not true for the EB. The EB uses liquid/oil cooled turbos that do not require a turbo timer or idle for 30 seconds to get the turbo's cooled down. If you want more information on this subject the try this Garrett website on liquid cooled turbos.
======================
it's not that hard to imagine the same oil that circulates for the turbo's after engine shutdown might be also be used in a similar fashion during ASS
it's not like FORD hasn't seen this solution in the past ...
