Evo 6 - Cold air intake

Hi,

pretty basic question which I think I know the answer too, but want to make sure I am not over looking anything.

I am thinking of moving my battery and putting on a cold air intake (K&N) for example… what else do I need to consider or is that is?

Putting a free flowing exhaust on too. So I imagine between the two “updates” it would be worth having a map to straighten out any problems later on. I don’t think I need fuel pump upgrade or is that a standard thing to do at the same time?
Thanks
