Large Intake Leak?

[QuickSilverGSX9]

I believe I have a rather large intake leak. I tried pressurizing the intake from the TB elbow on (I won a MachV intake leak tester from GT6), and it won't hold any pressure, I believe the most I got was possibly 1-2 psi on the boost gauge. The engine was at TDC, so all the valves were closed, and I heard no hissing, so all I can think of is that it is a rather large and obvious leak. However, after putting my hands all around the intake manny and throttle body, I can't see anything at all that is wrong. Could I possibly have something with the EGR hooked up wrong, or possibly something wrong with my valvetrain? I'm at a loss here. Any ideas are welcome.

If you had a large intake leak your car wouldn't start and if it did, it would surely die soon afterwards. May be the stepper motor not fully closing the valve or bad throttle body seals. That the only thing I can think of.
