so you can run the boost gauge line off the comp housing or wastegate actuator line if you want - because that sees vaccuum as well. <- No actually you can't, plumbed to the comp housing the gauge will see compressor pressure not manifold absolute pressure, all intercoolers restrict some flow/induce a pressure drop...Fail; Plumbing to the wastegate will see fuck all boost (<7 psi) because of the way the system bleeds boost (pressure) to keep the waste gate shut, you'd only see spikes as the systems pops the gate open.

what ebc or mbc are you using?

what is stock wastegate spring boost pressure? cause im guessing that is all you are using to control boost especially if spring pressure is about 0.4bar
You need to plumb off the intake manifold for the boost gauge to reflect what the engine is seeing....PERIOD.

Simply T off any of the barbs on the front of the manifold.

i have now changed the location of the boost control feed to the inlet manifold and getting normal operation.

boost is peaking at 0.7 bar.

Things to check next?

On the hand controller:

ETC. >
Function Settings >
Boost Kit <top item> <---make sure it is set to on
(Default is OFF)


Turn offthe O2 feed back whilst you there, It can make you go lean on boost.



Now for the boost settings.....

I don't know what PFC experience you have, so here's the best way to explain it.......




First column is boost profile (Profile #1 highlighted in image),
Second column is target boost in kgcm/2 - (start at 0.8 for safety)
Third column is duty cycle - (Start at 40% & work up to reach your set target boost)

fourth column is self-learn (always 255) & not user adjustable

The item selected (highlighted) is the current boost profile (you have 4). When you leave this screen whatever is selected is the boost profile the PowerFC will use, so be careful not to stray away from the profile you want to run..

What have you set as the Wastegate duty % for 1.3 ?

looking at mine the wastgate duty is 46% for 1.4 & 58% for 1.7

Up the duty % 2% at a time until it begins to have an effect (lifting the peak boost).

HTH Tris

P.s you won't see any vacuum between the Intercooler & T/body, the vacuum is behind the Throttle butterfly.

Watch your Knock values! safe is < 35.

Do you have the stock airbox & Subaru AFm on it Tris?

If so, switch the Airflow meter to 'SUPER INTAKE' which will make it run a little richer on boost.
