Interesting but not exactly the comparison we need. Or something dosent jive. According to the graph it was a v3.31 apr turn vs dm k04 on the same car and it's listed as a tsi. APR never released a v3.31 tune for a tsi, that would be an fsi tune. Given the graph was 4-29-14 posting at best it was a version 3.0 apr tune vs an unknown version of the dm tune if it's on a tsi. The apr version 3.1 tune didn't officially drop 6-16-14. So I'm not sure what comparison this is? Was this an fsi dm tune vs an fsi apr tune, or an apr v3.0 vs dm ko4 v????
