floor it, a sec or 2 later a boost ?? is this right?

lets say I'm in 4th cursin at 3000 rpm's, then after I floor it a sec or 2 later (@ about 3400) I get a boost of power. I'm just wondering is it supose to be like that? is that just the way this Cam is?? or do I have somthing wrong? I had Livernois tune the car so I don't think I should have to mess with the timming? maybe the gap on my spark plugs?? cause I'm not really sure where they should be set. Any help would be great.
