there is torco fuel additive. they make an unleaded additive that I used in ms3 for higher octane maps, worked great!!! it's just expensive.

If it works, people will pay. Better than paying the same amount for snake oil.

yup, I paid the money for it. if something like a feul additive actually works then it's worth it. I had noticeable effects from torco, I love the stuff:-)
