It's what I'm doing at the moment. I just call it street tuning instead. As long as you can find a decent quality flat road that is minimal to no traffic, no cops, and long enough that you can do a 3rd or 4th gear pull to redline-ish. Preferable an industrial area on the weekends when there's no one working and little to traffic or empty highway if you can find one at a suitable time.
A dyno is just a more safe, closed, and controlled environment for a price. Whereas on the street, road conditions may not be perfect (bumpy roads, sloped roads, temp variations, etc) so you are taking a bit more risk and it's less controlled. You may get busted by a cop during a pull, annoying locals can snitch on you if they think you're street racing, driving them crazy with a loud exhaust, or think you're acting dangerously on public roads. Or you get in an accident if you lose control or something unexpected happens.
Stage 1 and stage 2 are more marketing terms IMO but typically an off-the-shelf tune suited for a stock car or a certain set of upgrades (intake and catback exhaust, headers). A custom tune is tailored to your car according to how your engine behaves and the aftermarket parts that you have. Since no engine performs the exact same way, variations in gas, and every aftermarket part performs different.
I have the OFT stage 1 tune with a perrin air filter, trd catback and jdl uel catted headers so I'm refining the OTS tune so it's suited to my car specifically.
