I've just finished prepping mine for a trip to North and South America including Alaska.
Its like a barge and it has been chipped (ECU flash), had a power commander fitted and been dyno'd.
I have an extra 10 HP at high revs and an extra 25hp mid range in the lower gears, i.e. no dip . It is unbelievably quick and nice to ride.
5th gear power curves (8 hp extra at rear wheel = approx 10 hp at crank)
2nd gear torque curve........ Wohooo....
