What do you need it for? 1G is the same thing except the "lower port" is cast into the BOV and the source is the UICP (the hole next to the valve on the flange side of the BOV). Many poeple intercept that port and put a mipple on it, which make it function like the greddy in a way. We tend to use DSMlink or a switch to control when that lower port sees atmosphere and when it sees boost. Getting OT I guess though.
