Got a question on which one will fuel harder n longer throughout the rpm range. A Smarty/comp stack versus a quad box. Any info will be helpful n i know the quad box will fuel to 4k that's what I've heard but not sure on the Smarty/comp stack.thanks

 

Id stick with just a Drag Comp.

 

I have a edge comp now but it is starting to mess up. Should i just send it off n get fixed n hot unlock
