warn piston rings is usually the cause when black/bluish smoke comes out when accelerating...

on deceleration, it's usually warn valve guides...late

how much mileage is on your motor? really sounds like you're burning oil

Edit: Actually, you said when you "gun" it. Doesn't a stock car with vtec run rich or richer when in vtec? That could be the reason behind the black smoke.
