Hi kinda new here, thought this would be a good place to go for some knowledge. I have a 2015 GTI autobahn with the DSG it is stock right now but I am currently in search of a good tune to unlock some potential. I am only looking for stage 1/1+ type of tune something along the lines of eurodyne or apt. I have also just found out about OTS Cobb tunes that has me pretty intrigued because I like the other features you get along with the Cobb such as the dials and data it can display. The trouble is i currently reside in Anchorage Alaska and the best gas I have seen so far is 90 octane, and I don't really care to mess around with octane boosters. So would it be ok to run with a 91 tune? Or is there any hidden gems for this dilemma? Thanks in advance.
