hey just wanted to let you guys know, i got my spartan. i went from intake to exhaust, with a s and b intake 4" dpf and cat delete with duals, and the 250hp tune. its unreal. diesels mileage has increased but not as much as other people have claimed on paper im getting about 15-16mpg. one more question is i am looking into getting 37" tires. if i put them on do i need to update my spartan files for bigger tires and which tune would be better to run??
