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! --------------------  QUOTE (Galcobar @ Oct 15, 2008 - 2:44 AM)  You want power but have no money.

is it electric or mechanical? if its electric, it need to be hooked up to 12V that does not turn off when you turn the key to start.
