You can look at lifetime average engine load in insite. If it shows above 45% or so then it might be better to put the bigger injectors, pistons, and valve cam in but otherwise its not worth the extra expense (few thousand by the time you get injectors and have no cores to turn in) if ya ask me.

The engine will also be overall slightly less fuel efficient when you do this too when your not heavily loaded.
