Honestly, It could use more work. When you get to about 6500 RPM, the sound has a weird 'electronic loop'. You can here the sound loop easily. Not only that but for some reason it has a supercharger whine to it, but in many Youtube videos/clips it doesn't. I'm giving this three stars and criticism because I want this sound to be accurate and stay true to the C5R and this sound mod has so much potential. I like it so far, and if it can get an update with better improvements then my rating will change. Good job though!
To make this sound matching properly to legion's C5R, I propose you to download an optional
pack with some updates on data and visuals for the car.
