I saw a thread saying the OTS tunes were about to be updated and given the threads about Stage 1 vs Stage 2 tunes with only a midpipe, I emailed Cobb. The reply was "if you have an upgraded y-pipe then you will definitely want to change to the Stage 2 mapping." Have the tunes changed?

technically they are correct, stage 1 is for a completely stock car. Adding a midpipe is modding the exhaust so it's stage 2... On DBA's the stage 1 map was better, but I think that was a tuning issue on the OTS map. On my CBA, the Stage 2 map was better...
