fuel wise it sounds about rite mate, i get about 75 miles combined to £20, 60+ around the doors.

i did watch your video, its hard to tell, as with mine having the blueflame and decat, mine revs quicker.

if you can afford it at some point, i cant recommend a stainless exhaust and decat highly enough. this is a vid my mate took just after id fitted my decat. gives you an idea of the sound, although i wasnt ragging the tits off it.
