If like my S4 the standard and even DP fuel map is crappy at 30mph then moving the gearing either way will make some improvement? I left mine standard as I like the gearing just didn't like the fueling so I had it re-mapped. I know the later 696/796 suffer more because of the Lambda sensors making the mixture even leaner. So get those disabled and re-map would be the best way to go imho, then it wouldn't matter what gear ratio you had you could change it to how you wanted, but the standard is usually ok at least with the 6 speed close ratio box on the S4 its fine.
