My experience with default PowerCommander maps has been that they are obnoxiously and unnecessarily rich in the part-load cruising region. (On a bike that was obnoxiously and unnecessarily rich to begin with, they did not address this.)
You are better off editing the maps yourself rather than trying to find a nonexistent map to address this.
Now ... important question. When you originally got the bike and it was doing 250 km per tank, and now it's only doing 160 ... What changed? Did that change coincide with installation or mapping of the Power Commander? If it did not change with the installation of the PowerCommander, what DID change that resulted in this difference?
I am going to ASSume that the 250 km per tank was without the PowerCommander installed, and then you installed the PowerCommander. If that is the case then you have a screwed up map installed. If the situation is something else then explain the missing piece of the puzzle. What changed?
If the problem is that you have a screwed up map ...
First fill the bike with the most oxygenated fuel out there ... Sunoco/PetroCanada Ultra 94. (I never use this fuel for anything other than calibrating for how lean we can go ...)
Connect your laptop and cable to the bike and start the PowerCommander software with the engine running / key switched on (whatever you need in order to access the map). Save the map to your laptop as it is right now so that you have a known state to go back to if something goes haywire.
Now, go down the 0% column at all engine revs starting with 1500 rpm all the way to redline and subtract 5 (in absolute terms) from each number in that column. By "in absolute terms" ... 8 minus 5 is 3. 2 minus 5 is -3. -7 minus 5 is -12.
Do the same thing for the 2% column, 5% column, and 10% column.
Now go ride the bike and see if there are any driveability issues when cruising at various constant speeds or in gentle acceleration. The engine load at such small throttle settings is so light that you need not worry about doing damage. Feel for hints of surging or hesitation, which are the symptoms of being too lean. Chances are, it will feel exactly the same, maybe even better (if my suspicion of being too rich is correct).
If all is well then repeat the same step again. You can keep right on going leaner and leaner until you start feeling signs of flat throttle response, stumbling and hesitation on gentle acceleration, surging at constant throttle cruise, etc. If you get such symptoms, note the RPM at which it occurs and take a guess at the throttle position. Since you know the setting 5 higher than this was OK, try adding 3 (in absolute terms ... once again, negative-12 plus 3 is negative-9) in the RPM range in question. Go a little above and below just to make sure. Repeat, repeat, repeat ...
Once you have all this in the ballpark, feel free to use the 20% throttle position column to blend whatever you found for the 10% throttle with whatever is in the 40% column so that there is a smooth transition between your new "lean cruise" part-load map with the "power" settings at 40% throttle and above (which you should not touch).
Expect this to take a fair bit of trial and error. Expect to discover circumstances months later that you hadn't originally anticipated and thus needing to make further adjustments. You are NOT going to find any such map pre-made for you. And NO dyno shop is going to take the time that it's going to take to do this, and you wouldn't be able to pay their price even if they would.
My ZX10R map developed in this manner has some parts of the map at -35 (taking away 35% of the original fuel delivery) ... after about a month of tweaking followed by discovering at the drag strip that a long coast-down period resulted in the engine internals cooling off to the point of causing a lean-misfire (a circumstance that I didn't originally try out). Power is unchanged (because the full-load part of the map is not touched), driveability is impeccable (because I'm fussy), it doesn't run hot or detonate or do any of the other things everyone warns about when using lean cruise (they're doing it wrong), the engine oil no longer smells like fuel when it comes time for an oil change (translation: excessive fuel is no longer washing the oil off the cylinder walls and getting into the crankcase), the spark plugs no longer turn black, and fuel consumption has improved from 7 -8 L/100 km to around 5.5 L/100 km and that's despite putting drastically shortened dragstrip gearing on it at the same time ...
