Hi there
Modern turbo cars generally cross-check the actual manifold pressure against a pre-determined target pressure table, and adapt the boost pressure accordingly. As a result, the turbo on your Kuga will need to deliver less air at sea level (because there's a higher atmospheric pressure, it doesn't need to boost as hard), which should lead to lower intake air temperatures, reduced consumption, and improved performance.
That's the theory, at least. But the reality is that the engines are optimised to the extent that you'll likely not notice any difference, except for a little less turbo lag at sea level (again thanks to the higher atmospheric pressure) and quicker boost response when overtaking.
But the bottom line is this: The engine needs a certain amount of air and fuel to produce power, and whether the air is highly-pressurised or not, getting to a certain output level will always need the same amount of air and fuel. So, even if sea-level performance is slightly better, the consumption should remain the same - provided you don't use the little bit of extra power on tap. Keep your driving patterns the same, and the difference in consumption will be negligible.
Hope this helps!
