It's more complex. Every IC causes a pressure drop which is normally compensated by the charger, so it has to produce more boost ( and heat ) due to the IC. That's why I really look for VT1 non intercooled boost temps and VT2 intercooled boost temps to compare. I don't go for huge power increase, where the IC may be obsolete and in case tracking would be an issue, water injection ( not water / meth ) would do a very good job as well, IMO.
I'm sure ESS knows everything so I'm looking forward to them for chiming in. Especially the high CR of the S65 makes this engine more prone to detonation going FI than other engines.
