I also plug in the block heater every night on a timer which runs for 5 hours and than shuts off. I like a warm truck in the AM when I leave in the truck in the morning.
90 minutes will get you the same results and save some cash on the power bill.
If you have an 06 truck an EFI will work better for you than a Smarty will. The new Smarty are all emission compliant. Or if you just want a code reader and able to read and delete codes than the AlfaOBD would work too.

I disagree, especially for a 5.9 (there isn't emissions vs non-emissions 5.9 tuning or tuners). But what smarty are you talking about? SJR, S06, SSR, Touch, MM3? Smarty is the brand, not a specific tuner.
It does depend on what he is looking to do thou. If he just wants to enable the high idle then finding someone with smarty to tune and detune is the cheapest answer.
If he is looking for a simple tune then a Smarty Jr is still cheaper, but it sounds like he's planning to keep it stock.
If he wants a custom tune then a Smarty MM3 with a Custom UDC Pro tune will be better than an EFI Live tune as well. Total power between EFI and UDC Pro can be the same, however UDC Pro offers more tuning tables that are beneficial for day to day driving. I've done plenty of UDC Pro tuning for guys that were unhappy with the day to day performance of their EFI Live and tuner...
Not saying that EFI Live tunes can't be great tunes, it's just that UDC Pro tunes can be better. In the end a lot of it comes down to the tuner. Many "custom" tuners aren't doing anything custom for the end user as they are selling the same basic tune to everyone. This does go for UDC Pro, HP, and EFI. Finding a good tuner is important.
UDC Pro is platform specific to Cummins and EFI is not.
