Anyone one know if a 15-16 3.5 thermostat is the same as the 17 raptors.
Found a 140 thermostat and thinking of installing

This might not be a good idea, 140f is pretty low.

If you go to low it wouldn't allow the antifreeze to to stay long enough in the radiator to cool down at all.

Why so low? Without tuning you truck is not going to be happy.

Too low. Not a good idea.

165 might be a little low even. I think 170 is about as low as I see most ecoboost guys running and most are tuned.
