To answer some of your questions, you don't have to return to stock to update the tuner, I never do and haven't had any issues. 4wd shouldn't give you any issues. The tuner basically only adjusts fueling and timing advance (and some transmission shift points ans TM, etc....) so all other functions of the truck remain the same (4wd, tow/haul mode, etc...). All you really need to know is to have the correct octane fuel for the tune you are using, and make sure you never tow or haul heavy loads with the performance tunes. If you will be towing/hauling make sure to re tune to either the stock tune or the tow tune. Also, I believe you need to run 91 octane with the tow tune.
