Is that a 5.7 when a car intake? What I see in the picture is on the left side of the engine (driver's side is always LH). On a truck, that's not there, it's on top....and is for the EVAP system purge valve. It should be capped if the EVAP has been eliminated.
Is it possible the idle, etc. in the tune was set with that port open?

that should be capped off. if you have a 02 motor then the intake you have is the ls6 unless someone swaped it on you. the wieand intake is junk compared to the ls6.
capping it and it bogging down is in tune or setscrew on TB
