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!

my couplers are from vibrant performance, and I believe my pipes are as well. My blow off is the real deal Tial Q, hopefully putting another spring in there will help (A friend has some lying around) from what ive read on Tial's spring settings, i need an 10 or 11psi spring as the 3ssgte vac ranges from 18-20.

does that vaccum reading sound correct? I remember it always reading about 19 or 20 on the ninja turtle 1. and it was about 18 before taking the manifold off IIRC.
