You need the light one in for standard then the medium one when you get it mapped.

Start with the lowest resistance spring.
If you find the gear changes are too loud (ie dumping too much) or you are losing too much boost change to the next resistance spring.
Repeat until dump level and boost pressure is acceptable.
Putting in a overly strong spring will prevent your valve from dumping.
