In general, I really like your mods, since they have the detail that some other mods are missing. You really take advantage of the new way of adding parts to engines, and the parts feel (semi) realistic, which is really nice.
I also really like the way you show the parts your mod adds, with specs and all that, instead of saying "my mod adds an engine, it has much horsepower"
One final advice would be to change the intake of the diesel engine of the pigeon, since a diesel can't use a carburetter. If I may suggest something, I would say either high pressure feul injectors for more preformance and normal injectors for the default, or ( maybe slightly less realistic, since it would require a different head) have the default be an indirect injection diesel, and make the preformance edition direct injection. I understand that that might be a bit of a big change, but maybe you like it. The IDI could also be a different engine? (just an idea)
Please continue making these parts, i love tuning cars in beamng and your mods add many more parts to tune them with.
