If I'm only running two-bar right now, is that the one I should use? Or does the 3-bar OS have other capabilities that I should go ahead and use that one. I'm not sure about the level of choice I should make. Does the 2-bar sensor they shop got from the Chevrolet Parts place demand that I use only the 2-bar tuning file?
Eventually , I may decide to take my tranny to a 4L80E if this one breaks too often.
