TBI running rich?

I have a Vortec Headed 350 with an LT4 hotcam. It is fed by a 454 throttle body. It is running WAY to rich when idling. But the car seems like its running right? I know its a bigger cam and needs fuel.. But not his much. I'm using the stock 305 tbi computer, knock and map sensor. Does it just need a tune or what?
