I only do mine once in a while and usually don't do a retune. I just like to keep the files updated.It almost always downloads something be it a firmware update,fixing a glitch like this one,adding engine tranny combos,refining tunes,etc.So you may gain a benefit or maybe not.To me it never hurts to keep the data current.
