Well all of my buddies here drive cummins and one of them is known for having a really fast truck when really all he has is a Smarty, TST, and a Edge EZ with and we raced we were dead even! Then my other buddy has a pretty built truck (Twin turbos and what not) (no injectors yet but his 250's are on the way) He put his dual fueler on and drove his truck yesterday and the surpentine belt broke. Well look who had to pull him home through the hilliest part of town! The ole 6.0 is sure doing the job on the 5.9's. Just thought i would share with the fellow Powerstroke members!
