No one has the supercharger in their 5.7? A former neighbor had one in his 08; I think a filling of mine is still somewhere on US 17 after a ride with him.
they are serious mf'n business. my oil baron uncle sold his M5 and ended up with a charged big body tundra. that tells you something. if you have ever ridden in an m5 that is. insane. thank god for the yaw control.
