Hey AZ,
I have been running S1 for a little while now and love it with Milltek exhaust it has transformed this car totally.
I bought a Dongle and just got a chance to get it connected today and noticed that the only file I have is 93 while I don't plan on running higher octane. I thought I read that it would allow me to return it to the stock tune as well for emissions testing. Did my local dealer short change me or am I not understanding what the dongle does?
Thanks
