I'm wondering if anyone here has gone with a tune for race gas?

I'm in california and when I goto the track I'm not sure what race gas would be best suited for my car. (06 GT)

Would the highest anyone go be 100? 104? 110?

I've not been to the track in a very long time so have no clue whats available.. and the last time I used race gas was Turbo Blue back in highschool, some 18-19 odd years ago.

I'd like to get the xc2 ordered tonight and get that headed my direction.. but wanted some input from you guys till it gets here.

thanks

 

If you're going to get a tune specific for the fuel, go with the highest octane unleaded you can get.
