Sorry for the late reply guys. Anyway it is a 9750 we are working with. Got the rice accelerator up front,concaves and bars,and beater speedup like stated previously,and an airfoil chaffer which I think is another very important item. Also a 20% chip. Can't give any technical numbers because myself I have not spent very much time in the seat and the year has just been too crazy. Just been fuel up and go,go,go. I can say though that it makes the Kuchar modded 9610 look just plain stupid. Still have some whitecaps,but very acceptable levels. May play around with some filler plates if I have time. Overall,alot less returns,alot more power and capacity.Seems to be at least as good as the 9870's in the area. Good luck.
