Should I change these for after market ones after getting the car mapped? If I should, what advantages could I achieve please.

i was advised and run yellow spring on stage one map. Was given the info from forge.
I wouldn't bother with the 007p
The Bosch unit is perfectly fine and you don't have to service it or change the springs if you up your power.
The Forge unit gives a far cleaner operation it's a far superior part, the OE valve bleeds boost due to the diaphragm lifting unevenly due to it being rubber and it's design, plus there is no need to change the springs this is purely for fine tuning FOR THE PERFORMANCE MINDED! You don't need to change anything on these cars but there's no denying there are modifications that make it better than OE this being one of them FACT!!!
