hi i am new to this post but after looking at the dyno sheet it would seem that you are experiencing pumping loss at that rpm level it could be from many things port size ,intake runner size ,cam ect. then after that it could be that it recovers with just a touch of ram tuning ...at that rpm level when the power starts to fall off the incoming column of air still has much momentum so as the ram tuning takes effect it makes a slight amount of power and since dynos measure in times verses acceleration it has a slight power jump ....i could be wrong but i have experienced this in dyno work thanks for your time
