I personally never used one ,even when i had turbo cars 20 yrs ago,much prefer to drive the last few miles off boost,to allow the oil to cool the turbo down.
Pointless tat. Adopted by people here because they foolishly think that anything Japanese is purposeful. Remember Tamagotchi Pet? Pointless pseudo-useful gadgets fascinate the Japanese, but they get it, they know its tat really: but we seem to have swallowed it hook line and sinker.
Just drive off boost for last few mins of journey + leave car idling as you get out, remove stuff from car etc ie turn off as last thing you do before entering the house.
Thanks for your replys I'll not bother with the timer I'll just drive off boost, keeps the neighbours happy because I think a loud car ticking over for a few minutes would drive me mad as well
