Default Sluggish throttle response

My car has sluggish response when you punch the throttle. It's almost like it bogs for 1/2 a second or a full second and then goes. Also, the throttle response is not very linear at all. When you barely push the pedal, it's either not at all or a whole lot.

It's the same with the blower pullied or not pullied.

It's the same from idle or 1500 rpm with the pedal already slightly depressed. I thought it might be the cam, but even from higher rpm, it still does it. I'll give it a try from 2500 or 3000 rpm tommorrow to see if it does it there too.

The car pulls like mad, it's just the throttle response that stinks. Anyone have any ideas on what this could be?

Check my sig for more info....

Since you're running a blower, you might get quicker responses on the Forced Induction board.

essentially it happens if the blower is pullied or not.

Have you checked the basic stuff like ignition timing, 02 cross-counts?

Is your TPS voltage adjustable? What fuel pressure are you running? Are you MAP or MAF?
