When I first got the truck, my wife called it Cecil turtle (Green & slow). So several upgrades later and he now moves much better. Last night I put in 300HP injectors from Bully Dog. Installation was easy and what an upgrade! I can't imagine what the 375's must do! The only two problems I had were: 1) No instructions included & 2) I needed a 15/16ths deep socket. I can see going through tires a little faster. The turtle now has jets poking out from under that shell.
