#9This is a topic that often gets discussed and there seems to be belief that maps are radically different. The reality is that the difference(s) between any two maps (eg Akro versus Standard) is not that much overall. Clearly, any point over the surface of the fuel map can be different but in percentage terms dyno tuning probably only changes the value(s) by a few percent. In extreme cases it could be as much as 20% but only in specific areas not across the whole map. This of course, can have a big performance effect at any one point within the map but overall the maps are not consistently different. In fact, the two maps compared below only have 3% more fueling for the akro map if one looks at averages. When road riding you don't usually spend all of your time in the same area of the map.
What this says is that because maps for a particular setup are not going to be RADICALLY different (the worse case would be incredibly lean across a broad spectrum) using a map for a similar setup is fine. You can't really go wrong, however you can have it fine tuned for your location, air filter state etc.
I suspect that if I compared a bunch of maps for similar setups (eg just akro's) after they had been dyno'd the differences would be less than 1% in all areas (assuming the dyno people were competent and the bike felt ok). Maybe even less.
Hope this provides some insight.
