turbo vacuum lines

[TheFallen]

So I have a 95 tsi awd and I was rerunning all my vacuum lines. I noticed that there is a vacuum line running from the cool side of the turbo to the wastegate instead of running to the boost controler. I was wondering if this is a bad way to have the lines or if I should run them where they're supposed to go. Thanks.

Having the line hooked up that way just makes it so you only run as much boost as the wastegate is designed for. If you don't have the mods to turn up the boost, do not boost over 12 or 13 psi. U need a wideband and a way to control fuel as well as an upgraded fuel system before you even think up turning up the boost. The boost controller just allows you to keep pressure from reaching your wastegate until it reaches whatever boost level you set it at.

Ok. Thanks for the info. I'll redo the system and put it back to stock.

I would leave it hooked up straight to the wastegate actuator until you have a way to log and a wideband bare minimum.
