Turbo Timer ???

Here is a good one! I have a customer here that wants to install a "TURBO TIMER" :rolleyes: on his 2004 LLY pickup. Now I know what it is for. It allows the engine to idle for 5, 10, 15 minutes to allow the turbocharger to cool down before the engine actually turns off. I just haven't seen this in a light duty application. Do any of you have any ideas? Does Kennedy Diesel offer this type of programmer?

Could/ would the Webmaster of this website please post this posting in the medium duty section as well. I am really trying to help this customer out. Thanks! ;)
