info on decat please

so i have done plenty of reading on the n55 and what mods i want to do, cattless downpipes, with not to an offensive exhaust, wagner front mount inter-cooler and to finish it off cobb access port which is supported for my 2011.

the question is i am aware that it will throw codes and a dash light but does the car alter the fueling trying to achieve the sort off readings the o2 sensors should be getting, IE not running optimum fueling.
