i'm just after some advise if any one could help , i'm looking at buying a stage 3 step up for my cossie and it come's with a -34 actuator .
will this be ok for the set up or do i need a -31
thanks for the help

 

/31 and/34 are both good for stage 3 cossy /34 hold boost for longer

 

thanks for that stage 3 on it's way then
