The app is amazing. I really wanted to see more vivid colors on EFIS so they are more readable on distance and more "real".

This is one example. http://upload.wikimedia.org/wikipedia/commons/thumb/d/dc/Primary_Flight_Display.svg/2000px-Primary_Flight_Display.svg.png

I have ipad 2 and mini retina and both has same problem. Or is there setup allready for that? Oh and Eicas would be superb!

Yes brighter colours and larger fonts for the values as an option would be a great idea. It would make it look more like the real displays which are very bright.
