if you went from 4 degrees overlap to 8 degrees overlap, would you even notice a difference in the driving characteristics??or would the tune make it irrelevant

In a very general statement: rougher idle, loss down low, and gain up top.
Tuning always plays a big part, but those are inherent characteristics of changing overlap. The intake and exhaust valves will now both be open for a longer amount of time, making it harder to fill the cylinder at low rpm's and easier to fill it at high rpm's through the scavenging effect.
