any experience with a G2 Throttle Cam 400 on track ?

Hi
I have a G2 Throttle Cam 400 but I never installed it as I was pretty satisfied with the throttle respons after the Akra's came on

I only use the bike (a 08 SDR) on track and I am now considering what effect it would have to put it on ?

Would it be easier to get on the gas out of corners ?
Would it slow me down ?

Any experience ?

Thanks
