A good tyre helps.Ended with just over 170hp sae but picked up 8hp at 8300 and about 5ft/lbs torque.Didn,t lose power anywhere and was better from 1500rpm up.It was better or the same but never worse.Part throttle torque feel is better and smoother apparently.Dave is currently doing 2,5 and 10% throttle runs to get consisitent tre air fuel differences.In summary they take about an hr to fit cost a bit and feel better straight away and benefit from mapping to suit. <i></i>
