Also be aware that any engine components that may fail as a result of careless adjustment are not likely to be warranted by the manufacturer.
Does cold weather affect turbo boost?
As air temperature increases the density of the air, and the amount of oxygen it holds, decreases. This means that the turbocharger has to work harder, spin faster and compress more air to produce the same amount of boost it would at lower temperatures.

What happens if you run too much boost?
Increasing boost (within reason) will force more air into the engine, so more fuel can be added to increase the power. So in general, if you add more boost and have an engine tuned to suit will give you more power. Too much boost can cause turbo or engine failure.

Boost weather is the sweet spot between about 40 degrees and 60 degrees where turbo cars will see lower boost air temps and hence more timing, and thus more power, but not so cold that high air density at cold temps becomes an aero drag impediment.
