I think I'll go get the test flash before the haul up to summit for the 12 hour. we'll see how it does for that. I was just wondering if anyone had any luck, or if anyone had any horror stories. I'm looking to get a little more juice when towing, and maybe some firmer shifts, and maybe even a little better milage, is that possible?

What do you guys think?
I've only really heard of Bully Dog, I know there are several, Banks maybe, whatcha Know?
