so i have a buddy with an 07 6.0 truck and i've been tryin to tell him that he should get an sct xcal 3 tuned by someone like gearhead or innovative but he is dead set on the edge because he read that its the sh1t. can i just get some replies to show him at edge is crap. he also thinks everyone on these forums are hillbilly rednecks that don't know anything but those people at places like xtreme diesel are genius. if i can get some replies on some mods he should do i'll print them off even thought they will prolly fall on deaf ears. i appreciate your input.
