Boost Leak?

[Spooled238]

Yea i think i may have a boost leak, cause i seem to have lost power, and before my stock psi guage used to hit 14 at full throttle at 5k, now it stays right above 7, i may know the problem, could this be a boost leak?, there is a bolt missing out of my manifold that holds the turbo on could it be leaking out of that?, anyone give me some suggestions, i seem to have like 7psi, which i have my manual bc set at 13

Well my first suggestion to you is to make sure you pick up an aftermarket boost gauge that will help you alot, so you dont say things like "i seem to have 7psi"

if i where you i would check all your ic pipes, replace that bolt in your manifold and check your vac lines. then if you cant seem to find the leak you might want to pressure test your setup.

The stock boost gauge is based on a mathematical equation and does not read actual boost pressure. I would suspect the ECU is not happy w/ something. I don't think the stock boost gauge would even change w/ a boost leak. The last time my stock boost gauge stopped working before it was modified was when my timing belt jumped 7 teeth
