after having it done on friday overall very pleased in gear acceleration is unbelieveable! from 40 to 80 in forth is unreall . had a few niggles on saturday with it hesatating under acceleration have spoken to superchips who instantly asked could i take it up to their HQ and stick it on their rolling road to see what its doing! but have to say its settled down now, i went out for about 60 miles yesterday and it never missed a beat! just been out today for half an hour and still fine so have to see what friday brings on the RR.
