Making power on a FI can go a couple of routes
its a balancing act and always has been
if you have a a high static compression you run a bit less boost and possibly a bit more spark
if you have lower compression you run a bit more boost and bit less spark -
so yes you typically will experience less lag on the former solution but also you will be limited on the amount of power you make
other factors such as bore size, combustion chamber shape, fuel mix formation, rpm, torque curve shape etc etc all come into this
every engine is different and even then there's no 'right' approach - just different techniques with different compromises
