I'm interested to know whats the better method of accelerating in an aspirated car.
In a N/A car this is relatively simple, lower RPM=less fuel can be injected so it makes sense to change early whilst still maintaining acceleration.
However in a turbocharged car changing up at low RPM means to maintain acceleration you're putting demand on the turbo, whereas you could accelerate gently to a higher RPM without needing the turbo. But which is better?
By my understanding;
More RPM = More fuel injection cycles (plus higher pumping losses)
Lower RPM but using boost = Engine goes richer to make up for more air in the cylinder
