Just curious...

Dunks,

Rockhopper is right, the chip itself will do precious little for the bike's performance, it's the other mods like fitting freer flowwing cans (rather than the standard ones with a restrictive cat in them) and opening up the airbox that will free up a few more gee-gees. If you do those things the bike will need a bit more fuel at certain points of the fuel map and that's what the chip tells the ECU to do.

As I say, fitting the chip alone won't do much at all. Having said that, even if you fit the whole kit and caboodle you may not notice much difference. My bike has DP exhausts and an opened up airbox plus a JHP chip. My mate Glyns is standard, we're both around the same weight and his bike is just as quick as mine with no mods at all.

Mine sounds nicer though
