im having problems boosting. im running a sohc zc in a eg hatch. i had a bad gasket on my exhuast manifold the small square one that goes to turbo, i replaced that and sounds like its hold up now and i don't hear an exhuast leak anymore. but the problem is im only boost about 1-2 lbs. in 1st gear and by 3 gear i max out at 4 lbs. i used to boost a steady 7 psi. i don't have any idea what could be wrong. any help would be great appreciated. thanks alot in advance.

 

Sounds like a boost leak, check the fabrication section for the DIY boost leak tester, run a test and then post back. Dont post unless you test ! j/k/s
