Would a fueling box be better?,if you are trying to get more smoke,no a set of DD3's will smoke much more than a fueling box,and stock injectors ever will. You want smoke get the DD3's,they are streetable,yet smoke when you want to. If you are buying both,do it once,go with the Edge Comp box,you may be able to upgrade your EZ ,gives you in cab adjustablity. I love my Comp.
