Pretty sure on my 2010 6.4 with my sct livewire my street x tune it producing a lot more power than my race tune. My street x tune keeps u back in the seat especially when u hit o/d. The race tune seems like it has to try much harder to make power, it smokes a ton on bottom end and will build 30+ pounds of boost but not go like I'd think it would.. Any input appreciated!
