Doesn't have to be a dyno but yeah you need some way other than watching aircharge to see if you're gaining power. Could be GPS acceleration, subtracting times from logs, track, program like Virtual Dyno that compares acceleration from logs. Just mentioning if you don't have dyno you aren't out of luck and there are plenty of other methods.
There are times when aircharge might even go up but power go down. Cam timing with boost and aftermarket cams this can happen with pretty easily. More boost being measure leads to higher aircharge calculation usually but sometimes with cam timing you will reach a point where boost will go up and power go down.
