When fitting electronic boost controllers on the zeds does it have to be dual solenoid or can you still fit single ones? I know dual is slightly better but was just wondering

Depends what comes with the ebc. The Blitz iD-III I have has a single solenoid that uses Y adapters to join the feeds.

Couldn't you just use a Y adapter in the vac pipes to split it off, I think I wanna use the Greddy Profec Type S again it's simple to use but a great bit of kit

That;s what the blitz does. Have a look here http://www.blitzpowerusa.com/techsupport/pdf/sbc_i-d_iii.pdf Page 3 gives the connections.

Ah yes so should be fine then cheers buddy

Doesnt taking the feed from the balance bar do the same thing as putting Y's in vac lines?

Except you need to take from the other side of the throttle bodies
