Sorry for the late reply. everything has settled down after a couple of weeks or even a month. But the top end is really noticable now. one guy wrote on here he forgot to shift because of the new torque curve and its true. it keeps pulling after 6krpm. in hene sight a b30 prob would have been better but would have cost me another 100 quid to do the diy. i havent readjusted the throttle cable again though. i think ill live with that.
