I have been wondering if a tune is the solution but i’m pretty sure I can’t if i want to keep the vehicle warranty.

Might be worth asking the dealer if they will tune etc, mate had this done on his dmax (probably 3 years ago now) from new and retained the factory warranty (unsure if the dealer did it or outsourced the work)
