i am stuck in the 1.85's
i just ordered another gallon too lol, i went out and checked my supply and i only have 24oz left!
what i do is fill up my tank, add 2 bottles and drive to the track (about 180 miles!) then by the time i get there the car is used to the higher octane in the tank and adjusts the "tune" to accommodate for it.
So what this is telling us is that 93 just isn't cutting it for this setup? Probably pulling a lot of timing in the upper RPM's.
