To get the tuning back, you need to edit " carcols.meta" and " carvariations.meta" in the mod itself. Namely, replace in " <kitname>501_infernussr_modkit</kitName> " and " <id value="501"/> " 501 with 987 also in " carvariations.meta" replace 501 with 987 in the line " <Item>501_infernussr_modkit</Item> ".
