Heres a link, I thought about getting one, but was quickly advised by fellow FTE'ers that unless youre towing heavy loads, the timer wont do much.
But if YOU are towing a lot, it could be a good idea.

Personally I don't see the need for turbo timers on diesel trucks.
The turbo timer is supposed to help prevent coking issues with turbocharged engines. Coking is that oil that remains in the hot turbo on engine shutdown, and burns, leaving behind a nasty mess inside the turbo bearings that eventually destroy it.
Problem is, try to find coking issues with these trucks. It's one of the rarest problems you'll ever find on the 7.3L.
The reason coking is rare on these trucks (and many diesels in general) is that diesel run at much cooler EGT's than gas engines. Turbo timers are better suited and sometimes needed for certain turbocharged gas engine applications, as they run much higher EGT's and end up heating the turbo far more than a diesel. Even those who tow heavy won't see a problem or really have a need for a turbo timer.
Another reason coking is rare is in conjunction with the lower EGT's of a diesel, oil itself has vastly improved over the years. Oils are more tolerant of higher heat, and thus less subject to coking issues.
Ultimately it's up to the individual if they want a turbo timer on their diesel truck. It doesn't hurt anything, but don't expect it to add longevity either.

I think that the oil coking issue is why Mercedes, VW, Audi all mandate that synthetic oils be used with there diesel engines. It might be worth switching if you are concerned with turbo charger issues.
