I'm lucky and have access to 93 octane!
And just the normal launch ahaha asc off, sport, easy on the break were the car is almost moving, boost for 3 seconds (to avoid that slow down message) Have you had that happen to you before? I actually have a new tune with a cat delete and hopefully will be hitting the track again! maybe going a little faster
What mods are you running? Whats your launch method? What kind of time are you getting?
