HP with Datalogging? Tuning People?

Well there are programs like eec analyzer that you can put in tire size etc., with that, if possible logs of engine rpm and mph/kph, etc. you would think you could better estimate horsepower.

Really when you think about it, what does a dyno do exactly. Like what does it measure, tire turns, speed of tires, torque, and other sensors maybe.

Just thought it was reasonable to assume that people who do real time data logging would probably be able to better estimate or come close to approx. combo hp with these tools. Rather than just a short sighted guess of what there combo makes in terms of hp.

What I am pretty much asking is, for a good tune with real time data logging capabilities etc. Is there really a need for a dyno.
