At the 1/4 mile track with a JB3 335i

What setup should I run on my JB3/car for the best times as far as octane boosters, race gas, tire pressure, etc?

I'm going to have less than 1/4 tank of gas in the car so how much race gas should I mix in?
I think the track offers 100 octane and 107 octane (?).

Other than that, I will be running map 7 I guess, and in DS mode launching at 2.5k rpm...?

PS. All I have is a BMS intake and the JB3 on my 335i.

I think anything over 100 octane at the track is Leaded. You probably don't want that. If you're gonna worry about how full the tank is then make sure you poop before it's your turn. every last lb....

shift well before redline. I don't know what to say about pressures besides monitor and ask the other guys there that are doing well on similar street tires.
