what is "boost"? my car does not have that

It's the KERS (kinetic energy recovery system). It's battery power that's collected from braking (perhaps some other additional sources) that can be released by the driver when they choose. Similar to F1 car systems in the early 2010s.

Intake pressure provided by the turbo or supercharger - basically exhaust gasses spin one side of the turbine that causes the other side to pump air in to the engine at higher-than-atmospheric pressure.

This allows for more fuel to be added for more bang per engine stroke!

It's not that. You only see the "BOOST" indicator when coming out of curves; if this were a turbocharger you'd see it all along the straightaways.

Someone else mentioned KERS (kinetic energy recovery system); that seems a lot more likely.

It’s the amount of boost provided by the turbocharger. Your car very well may have that.
