Turbo wastegate

[DennaGT175]

Hey guys...anyone here help me out..
Is there a difference on the megane 225 turbo actuators and the megane 250/265/275 actuators?
I've seen some come with different colour dots on them..
Whats the difference and why?
TIA

Yes, there is a difference to do with cracking pressure. Green (250 / 15 T ) and black dots ( R26 / 14T ) for them.
