When i get a remap will i need to change to a yellow spring? If so why? I currently have a green spring in.

They allow the DV to open at different pressures.

Yellow spring is for 19-23 psi i believe which is what you will be running once mapped.

EDIT:

Valve Spring color coding

Green - 5-15 PSI
Yellow - 15-23 PSI
Blue - 23-30 PSI
Red - 30 + PSI

car will explode!!

nah i think it might limit the boost, not 100% sure though

i think most mappers supply the springs when remap a car

ran green spring without problem after stage II map

have a yellow in there now which seems to react a little quicker but had no problems holding 19psi with the green spring before.
