I'm trying to decide who to go with for the tuning on my track hawk. I am going to run flex fuel and 93. Both tuners have great records and proven results. Barth adds a flex sensor while Dusterhoff uses the wide band. I'm gonna be running id1300 injectors, 2.85 pulley with jokerz ported snout, jlt intake and stainless works pipes and a dual boost a pump... I've read so many posts on many forums and have watched sooo many videos on youtube. Its a hard decision.. Any reason you would recommend one over the other?
