Well here's my impressions....
I was running OEM Pirelli SPs. Race mode, DTC3 ECB2 DWC3 ABS1
My first feeling it was the way my rear wheel drifted in a 90 degree corner. It felt natural...not a rough hook up, continuous and smooth.
second place I saw it was driving up hills on the top of the tire.. Even with DWC 3, the front leaves the ground, (probably a 1/2" due to the CF wheels), so then the DTC light goes off, which means to me that the DTC was working with the DWC. This happened serval times, so I either am spinning up the rear on the top of the tire, (which I couldn't really feel) or the system works together more completely. Also, both the QS and the auto Blipper work better...I get pops on up shift from time to time if opening throttle while shifting, The auto Blipper seems to add a few more RPM to keep it smooth and seamless.
There is definitely a difference. I will need more track time and to set my bike up a bit better but it will all have to wait till after I get healed up, I get my shoulder scoped on Monday.
Do I think it is worth it? For me yes.. It felt different enough, ( in a better way) for me to be satisfied.
