Re: 900RR Horse power
sorry to rant - perhaps more inline with what you asked..
getting higher peak power is a cheap trick if it's at the expense of low and midrange which is where you spend most of your time if you're an average schmo - like most of us.
since you have a full exhaust system on there maybe there's some merit in tweaking those jets to get the most from it but if the bike felt nice with the new exhaust and stock jetting why go through the extra aggro?
Anyway if you do wanna stick with this, for your money you're looking for an overall higher and smoother curve throughout the rev range and little or no 5.5k dead spot (as I understand it this dead spot is tuned in by the manufacturer for no other reason than to get through emmissions control) often and aftermarket exhaust is enough to get rid of most of it. If that's not what you got then it's not right.
If your tuner achieves just that, even at the expense of a little peak power you'll still be ready to believe anything the dyno operator says and more importantly your ride will be massively improved. I'm not qualified to dis dynojet but those kits are expensive, a good tuner will probably have jets and settings lying around for all that and you needn't necessarily have to pay out for a "dynojet" branded selection.
