I disagree with this 100%... I have had the Volant for most of the time I've had my truck (a 1 owner 2004, bought May 2004) and I have performed better than most Stock trucks on this forum the entire time I have been on here. Years before I did any lightweight tricks, like back in 2006 at the first big GTG I was the only NA truck in the 12's (ran a 12.64 that day) at full 5,000 lb race weight, including full interior and a bed cover. I did make an extra scoop (Ram Air behind the grill area, straight into the air box) and I have consistently had a better MPH that all the other NA trucks on this forum.
