Anyone use it? Is it just a plain old octane booster that you can get at the auto store? I need to increase the octane for my nitrous so should I try this stuff from MX or use toluene? Says it increases the octane rating by up to 20%, which is quite a bit. Hard to believe since thats going from 91-109. I was "told" that octane boosters were bad for fuel solenoids, but NX has their own.....
