I found some better low revs sound videos especially from Kristo Boginski, and so i was able to make my engine sound more realistic. The changes are these ones in v1.2: -New sounds samples from 500 to 1600rpm. -Lowered the air brakes, and blinkers sounds. Exterior sound is the same since i have nothing new to add on it. I hope you will enjoy it. Have a good trip!
