Default Cam lift and FI

I am quite new to the FI world so always better to ask.

I've heard some people say lift isn't as important in FI, if so how and why is this true?

In my opinion if you have less lift you will build more PSI in the manifold due to the restriction compared to this PSI being built up in the cylinder....

Correct me if im wrong but this makes sense

The more duration contributes to back pressure issues sooner.

I would stay away from general statements and that's about it.

Not a damn thing wrong with lift provided the rest of the valvetrain can handle it
