not building boost, am i missing something? Options

[easternpiro1]

Hi all, was wondering if i can get some feedback on something i was missing. here's the story:

recently a friend and I fixed a leak due to stripped thread in the head causing a leak between the exhaust manifold and block.

after rethreading and putting everything back togehter leak is gone BUT now im seeing much lower boost numbers after taking it for a drive.

I own an AEM tru boost controler/gauge and the boost is currently set to stock wastegate pressure (8psi) and consistently held this pressure PRIOR to fixing the exhaust leak.

as of today, my first drive out, my car would not pull past 5psi and touched 6psi BRIEFLY. I double checked my IC piping and adjusted and retightened.

when i went back out the car would only boost up to 4-5 psi adn sometimes as low as 2-3 max.



Im pretty sure its a leak somewhere but it can only be one place as the only IC piping that was removed was the piping coming from the turbo (charge side) i have checked and double checked it.

is there something im missing? any helpful hints would be appreciated! thanks!

yeah, Its not actually hooked up to any boost lines to control anything yet. I have the instructions on video via Youtube, so i will go over it again to be sure, but im pretty sure it was ok as it was accurately reading just wastegate pressure before the leak

Are you set on PSI, BAR or KPA?

There is also a setting there for internal or external map sensor, depending if you are running 1-29psi or 1-50psi. If this is set wrong, your gauge would read lower than it should.

im set to PSI. and im assuming as far as settings for map sensor internal is the way i will be going as i will not be running more than 29PSI

CHECK to see what its set to right now. If its set incorrectly, it would explain why you are not seeing at least 0psi.
