>if you post someone re-tuning a car for 8hp (they're just running richer gas at a higher compression) I'm going to mock you for being a retard.
A lot of times that restricts the gas that the car can use to only be the highest octane readily available.... and require a skilled tuner to make that tune for that specific vehicle.
The "tunes" on stock cars are designed for maximum reliability across the entire fleet. You bump up the ignition timing a few degrees and suddenly 10% of the entire fleet now has pinging issues when its hot out and the gas is kinda old.
You're not paying to unlock "the last 10%", you're paying for a guy to spend time to make a tune that is custom to your specific car... and also assume the risk that comes with it.
But those "mail in your ECU get it flashed" tunes are a load of BS IMO. Basically half of the subie world.

>you have the same engine capacity in models badged differently and with a different power output
Usually those engines have different cams and/or changes to the exhaust/intake manifolds to adjust how the torque curve is shaped. It's very rarely just a software thing... Although nowadays that may be different.
In all likelihood, it's not the "tune" that you unlock, but the last 20% of the throttle by fucking with how much the drive-by-wire throttle is allowed to open. They already do that for traction control and speed limiters and shit, so just putting it behind a paywall seems way easy.
