Well for one thing the scale on your graph is different than the scale on mine - which impacts how the results are graphically represented.
For another thing, I believe that each of these engines coming out of the factory are unique creatures - they all have slightly varying characteristics. EAS can probably be the first to testify to this - they've dyno'd a number of completely stock M3's with statistically significant variations in horsepower. That tells me that no two cars are built alike.
Finally, i would surmise conditions have some mild impact as well on the shape of the curve - though I can't say for sure.
Again though, I suspect that the biggest reason here is that differing scales of our two graphs.
