I copy a trim&variant of a car i have created and i change 3 things for the new model.
I increase boost from 14 PSI to 40.5
I increase fuel mixture from 14.8 to 11.1
I decrease RPM limit from 9000 to 8500
The engine weight stays at 230.5 kg the entire time
The car weight INCREASES from 1357 kg to 1447
Excuse me what the heck? My car just ate a grocery store somehow without my knowledge!
