How can you use Airboy to compare powerbands when there is so much smoothing that everything just looks like straight lines? Or, at best, extremely smooth, barely curved lines? If you just keep turning up the smoothing, then every turbo looks like it's going up, up and away at redline (and the further you turn up the smoothing, the higher the peak power numbers end up being).

I much, much prefer an actual dyno when trying to compare this kind of thing. But the Virtual Dyno program does a much better job at resolving an actual powerband than Airboy does. This is just my opinion, but I have a very hard time drawing any conclusion from such an over-smoothed plot. Also, I'm guessing that these plots are from different setups. It would be good to know what the differences are (motor, gearing, intercooler, fuel, ambient temps, etc).
