The '05-'10 intake manifolds occasionally have a tendency to leak vacuum at the rear where the CMCV actuator assembly is placed so you might wanna check there first. If that proves to be the case, an easy cure is to get rid of the CMCV assembly altogether and replace it with delete plates (Steeda delete plugs in your case as it's an '09).

Vacuum leak.

Thank you .will try that,

If you're repeatedly having to tighten down the manifold, are you tightening to torque spec? If you are and still having problems keeping it tight, your hardware's got problems.

Have you checked the gaskets?

And stop screaming...
