can someone plz let me know the routing of the vacuum lines to tial wastegate ?

i just wanna be sure of my set up

[isa alnoaimi]

i installed the 11 psi springs in the wastegate, but for some reason im boosting 20 psi .

im scratching my head over this .

i followed tial instructions for relying on the spring pressure method ( no manual boost controller)

[mittens]

You should have a boost only source (Normally a nipple on the compressor housing), that connects to the Wastegate actuator directly. (if you have a boost controller it would go in-between the too).

You blow off valve, and boost gauge should be getting a boost and vacuum source, like behind the throttle body/ intake manifold.

Normally most wastegate actuators, do not like to see vacuum. so its connected to the turbo.

How many turns on the waste gate actuator nut?

hmmm ....

i took the vacuum line from the intake manifold and this line is connected to the bottom air port of the wastegate .

is this right ?

or i should tap the turbo cover for boost source ?
