Honestly I don't think they will help on anything more than conistanicy, When the truck launches correctly I have the peddal to the floor almost instantly and they hook damn good, the hop is bad, but there hooked. I have to find a launch that wont eat clutches... Now after headers, sct and catback they will be needed, but hopefully with that set up I can go low 12's. Then comes my motor, and at that moment the truck is no longer my DD it's track only, 14:1 compression and just under 600ci, 900 ish horse power n/a??? I can dream....
