I have the Bama V2 tune installed, couple of days ago I was merging onto the interstate punched it to get ahead of a big rig. It accelerated real good but it hesitated in shifting gears but then lurched into the next gear. As I am a newbie to tunes that is the only wording I can explain to describe it.I'm using the sct x4 tuner. I have notice the shifting to be stiff. Is there something I can do with the tuner to make adjustments.
