Also, I'd like to see the power curve at that RPM. You might run on the track slower, revving that high, than shifting at the optimal time. All of this is just my opinion.
Engine is not stock... Thread is about bone stock OPTISPARK...seems like a lot of folks talk smack about how bad they are, however, my experience with them is totally different. That is a screenshot of a bone stock OEM OPTI at a high RPM. That opti is in a daily driven C4 and gets to see 6000 rpm or more every time its on the road.
