I have to do the same thing when figuring the primary tube length on headers... I try to get the best length on intakes when I build my own stuff

I would not think that's an issue with boost
just because there is more pressure does not mean there is no effect.this topic is for n/a also to think about.

I'm sure in a boost condition it would be minimal if any... same thing on the exhaust side (boosted engines dont need a collector)

A plenum-based manifold (anything other than IR) is far dirtier than the calculator accounts for. Each wave and its return interfere with all 7 other cylinders either reinforcing or cancelling them. Multiple traces of pressure changes occur constantly throughout the manifold and far into the runners. Read Blair.
