> you cant be as aggressive with tuning with meth as you would be with e85, but the principles are the same for the most part. higher octane, lower iats.

With meth injection you can keep your gasoline fuel mileage and other fuel system parts. Its cheaper than upgrading fuel pumps, injectors, and fuel lines for E85. Not to mention tuning.
