You can increase the base influence of towns by changing
"SettlementFoundationBaseInfluence": [
45.0,
150.0,
400.0
],
in Settlements.eco. Increase the first number. If you use a big sized world, you may need to set "ScaleInfluenceBasedOnWorldSize" to false first and take into account that currently existing influences were already adjusted to a degree, e.g. you need even higher numbers.
