Wastegate spring - standard or uprated?

[OOOO]

Hi all

My car is going for a remap soon and i need to know if i should be thinking of changing the wastegate spring

The engine is a newly upgraded RS2 spec ABY;
(rs2 turbo/manifold/intercooler/injectors/ with big exhaust, bosch fuel pump and 7a exhaust cam)
Im unsure - can it be remapped for maximum boost with the standard spring or is it better that it be a harder one?

Every engine reacts differently when being tuned, sure...
but then at least this should have a pattern - more boost or less boost.
Apperently it can vary

I have done a search but can not determine which is good for max performance.
Its worth pointing out that after asking a few people i have had different opinions so is it just a difference of preference?
And if it is just a preference thing then what is that preference based on?

When Mihnea re-mapped my car he supplied a 1 Bar spring for it.
