Talk:RR3 Wiki:Upgrades Strategy For 100% Completion/@comment-2405:204:B00A:D7B:F0D7:32EB:AC99:B98F-20180825070214

Sorry about the noob post but I don't get the "+" in the strategy section. I  understand the "-" as its straightforward e.g. -2 engine is 2 less engine upgrades from an FU engine.

But how is the "+" to be read e.g. in  GT1 Grand Tour the LAMBORGHINI MURCIELAGO R-SV GT1 has the strategy of "+1 drivetrain".
