The 58V just drives the injectors a little harder to overcome the stiction from what I understand. I've heard or read of some issues with the 58V during towing, but I think that's just internet jargon, since then most have reported the tow all the time with it, without issues. Swamps does good work. The only con is the extra cost I guess, but gotta pay to play. I'm going to be doing my own 58V FICM as soon as I can source the parts needed. Some of them are minimum qty of 1000 pcs.
