Did You Know That....

To boost from 91 to 95 octane, you need to mix pump gas with toluene in about a 4:1 ratio -- one gallon of toluene for every four of pump gas.

You can usually pick this stuff up from a good size hardware store in 5 gallon containers.

A 3:1 ratio will probably give you what you need.

Treat this stuff like gas. Don't leave a pop bottle of it rolling around in your car.

The alternatives would be to tune for 91 or install water/meth and return anyway.

If you're not running an after cooler, then that would probably be the BEST option (nearly forgot to mention the after cooler option).
