V4 mode does give a different sound on the 5.3.... I would not describe it as a drone.... Not sure how exactly to describe it.... I have a 75 Mile drive to and from work, all at 65mph... So I hit v4 a lot. I guess I would say it is like the sweet spot where the exhaust just hums along not droning, not over the top Ricer... Just kindof hums along...
