I have the mid package so I lack a few of the extra sensors but for the mid as far as I can tell as long as you don't block this sensor everything has been pretty well flawless
I have 15% on the fronts of mine with 20% over factory throughout the rear to balance the look with 50 over the windshield and a 15% brow strip....doesn't affect the auto high beams because that is in the box behind the rear view mirror...also mine seems clearer than any other tint I've used...
Just some food for thought since you wanted to see boost and mpg simultaneously....you can get a banks idash gauge and have it show your boost as well as many other functions and there is also a model that serves as a data logger as well
