What are the limitations of a power commander meaning what can or can't it do or what does or does not it do?

what are you trying to do? speed costs ££££ how much you want to spend?
Hindsight is a wonderful thing but foresight is better,especially when posting summat stupid.
I'm trying to get the throttle more smoother, will be changing the sprocket and putting an after market can on to I'm wanting extra power with out changing the bike to some more powerful
If you are going to change the end can and fit a power commander in an effort to gain more power you will need to increase the engines ability to take in more air so you will need to fit a free flow air cleaner.
No point in putting on an end can designed to increase performance as all it will do is alter the performance of the bike in a detrimental way.
Principle of tuning is to increase air/ fuel into combustion chamber in as large a quantity as is possible, get it to explode uniformly throughout the combustion chamber and then expel the spent gases as efficiently as is possible.
Easily said not always so easily done and as has been said it can get very expensive.
assumption is the mother of all f*** ups.
I think you're on the right track. Modern engines are hobbled by EU emissions regs. I bought a second-hand Power Commander from eBay for my R1. The second on-line map I tried smoothed out an irritating flat spot just above idle with no further effort. I haven't noticed any other advantages but the '03 R1 is pretty smooth anyway and it's never been dyno'ed. The map leaned out the mixture at low revs, filling the hole which Yamaha would never have wanted there in the first place.
Edit: I was talking about smoothness or responsiveness but I've just twigged that you're after more power too. For the money I don't think you'll get a big enough power hike to make it worthwhile compared to the other option you stated; buying a bigger bike.
i really enjoy riding my machine i don't want to change it for at least another 4 or 5 years.
