I am thinking about getting a 93 Octain fuel tune for my 13 GT but before I do I wanted to know if 93 is readily available in the Northeast? I live in Western MA and 93 is plentyful here but what about states like CT, NY, NJ, VT, and other eastern states? I would hate to get a 93 tune then take a ride to say New Jersey and only be able to get 91 fuel. I only ask about Eastern states as I most likely won't be driving across country anytime soon in my GT.

 

Plenty of 93 in northern NJ. I imagine the rest of the state is the same.

 

You can run the 93 tune but if at some point you have to fill up on 91, just don't run the car hard until the tank is close to E. Hopefully by that time you'll find a station with 93.

 

most of upstate ny is 92

 

Just make sure one of your 3 tunes is a 91 and carry the tuner with you if you travel. Or can't you save your stock tune as 1 of the 3 in a SCT (which adjusts for octane)?

There is no 93 on the west coast for example. But who knows you may find a small town station in NE when you need fuel that doesn't have 93.
