I have recently purchased the wastegate and a pg reworked turbo. My question is the stock wastegate has two lines running, one from the wastegate to turbo the other from wastegate to boost solenoid (or whatever it is). However the forge wastegate only has a single connection for a vaccum line. which way does it run? it seems most logical that it would connect to the turbo since the connection face the same as the stock connection to the turbo. any advice would be appreciated so i could put my motor back together
 
Well, how does that piece work? What does it do? Because it might just bypass the stock boost control system altogether (which would explain the lack of a second vacuum port). Not saying that's true, but if you know what the part actually does it might help point you in the right direction.
 
i know the upgraded wastgate has a stiffer spring for higher boost levels but nothing gives an indiction for lack of a second vaccum line

Mine has a tee fitting at the end of the vacuum line.
By the way, it is not a wastegate. It is a wastegate actuator.
It should have come with three different springs for use with different boost ranges. It will not cure boost creep, which is a problem caused by the wastegate itself not being capable of flowing enough exhaust.
 
First off run a t fitting from turbo off the line that goes in to the wg already and ur goin to need a mother peice of hose very simple install, it's a tight fit but that's how I routed mien but You have to set the preload on the wg spring because I just threw mien on like a rere and I was Maxing out at 12psi bc the wg was maxing out to quickly so I put the stock one back on for now till I have time to mess with it
