Does anyone use it to boost the octane to what Porsche recommends?
I know there are fake boosters out there that don't really raise the octane as measured by the Dept. of Weights and Measures, but there are some that actually do work. I just don't know if I should try using it or not.
Thoughts?

PS. ive had good results using the NOS octane booster Race formula in other cars w\ forced induction

Another gas war? LOL. J/K. Some people add some 100 octane liquid gold if it's available nearby.
