No appreciable difference with the 80e versus the 60e. The insurance factor is nice to have though!
Have you gotten the 4wd to work yet? I'm thinking about going FI and want to swap to a 4L80e with existing 4wd before I start slapping a turbo on the truck. PM me your cost so far on the parts/labor if you don't mind. What did you do about drive shafts?

Thanks
