how much boost can they hold, with this blue spring?

thanks..

blue is the middle one i think, there is the red spring as well which is stiffer.

they are working nicely on 2.1bar that i use. However remember that stiffer spring does not have to do with boost pressure, as when fitted, the boost itself is holding the valve shut. Its on vaccum that the stiffer the DVs spring will not allow the valve to open enough so part of the back slapping air from the throttle will be going to the turbosharger. So blue spring basically is more than enough.
