Ok, I've got a bully dog gt tuner on my 2003 7.3L. And as far as I've seen on here it's a p.o.s. But I've never ran another tune or rode in another tune. I don't want to tear my truck up with my bully dog, so I'm interested in looking into a new one, but I like the DTC trouble codes on the bully dog. Is there another safe chip with that DTC capability? Just need some reccomendations please.
