Getting my new '17 FiST delivered in the next day or so and want to do some basics immediately. Apparently the Mountune package is cheaper and better included tune than the Cobb package, does this sound like a perfect starting point and maybe add a Stratisfied tune later? Also, how much lee-way is there with the octane in these tunes? I'm in the Northwest and we get 92 octane premium, would I really get a lot of knock if used a 93 tune? Or should I add a little octane booster before filling up and calling it good? Sure, I can get multiple files of 91 and 93 octane for the AP right? But no one does 92 specifically I believe so it would have to be a custom tune? Any thoughts appreciated in advance!
