Got S2 Friday, installed it that night and drove just a little then and a little today..while I know it isn't twice as powerful as the S1, but oh man does it feel like it. wow! It could be because the S1 wasn't installed for a few days, and my car drives better after the last service visit, but it feels wickedly quick. So far so good.
FYI: start to finish with modifying the harness for the upgrades and reinstalling the whole thing, including disconnecting the battery terminal and removing the electrical cover. 45 minutes. My guess is slightly longer for those less mechanically inclined, but overall if you plan accordingly and remove the air-box cover it's fairly easy.
More to come…..
