I just got my SCT tuner back from SCT where I had it upgraded from a model 3000 to a 3015 tuner....initially I got a ECU not supported message so I called SCT and they wrote a custom file to allow me to load up my tunes. When I went to load my tunes I got several error messages and a message stating it didn't load my strategy tune. So I figured it wouldn't hurt to update my X3 unit using the SCT Updater program. Now 30 mins in I'm wondering how long this should take?????
