My uncle just got a 6.0 auto F-350. He came from a '99 F-250 stroke. He is looking for a tuner that tunes through the OBD port (not a chip) and can be taken out when he wants to. Specifically he is wanting better than the 13mpg he is getting now and wants to get rid of the slow response on take off. If it were a 7.3 I'd know what to tell him (see sig) but I'm not "boned-up" on the 6.0. Thanks in advance for the help! /ubbthreads/images/graemlins/shrug.gif /ubbthreads/images/graemlins/grin.gif
