I would keep the same "rate of change"(gradient) that currently exits in these rows above 17psi(~2.2-3.0) and just increase the whole lot by an equal %. At least for the immediate row im adjusting. For example if your starting at 2.2 ajudt everything above it also. If the next row is 2.5 adjust it and everything above it at the same time, and so on until you're at the last row.
The turbo mass flow rate can stagnate and higher Pratio depending on its design(slope of compressor map), so the difference between rows may not be very significant. The differences between colums should be more consitant since the only independant variable is RPM(more predictable change to ve) . So I'd adjust entire rows before zeroing in on the RPM.
The VE table is more easily thought of as just a "air mass flow rate correction factor".
