Congrats. on your new truck!
The block heater heats the oil in the pan to keep it from getting thick in cold weather. This is especially important for Powerstrokes because of the HEUI injection system. The injectors use the engine oil as hydraulic fluid to operate. If the oil viscosity is not correct, it affects engine operation significantly. Cold weather makes these trucks very tempermental for this reason so it is a must to make sure the glow system and fuel bowl pre-heater are in good working order if you live in a cold climate. (Otherwise, the truck just flat won't start in even moderately cold weather) I would highly recommend getting a block heater since you live in Indiana. The glow plug relay on these trucks is also notorious for going out and usually, you won't know even know it until the weather gets cold and you find you can't get the truck to start. (happened to me). So if nothing else, make sure the relay and glow plugs are in good shape.
Fuel in the valley usually means that the mechanical fuel pump is leaking. It sits in the valley under and slightly in front of the turbocharger pedistal and runs off of the cam. (again, also had this problem) The truck will still run fine but will leak out of a little hole on the bottom of the pump. The only option is to replace the pump.
As for the turbo whistle, if the truck is stock and does not have a chip, you will only hear it whistle when you really get on it, and even then, it is not as loud as the newer trucks. Since these trucks don't have intercoolers, the stock boost pressures are much lower than the new trucks. A few modifications and it will scream though!
Hope this helps a little, good luck with the truck!
