That seems counterproductive. The main reason for running WMI is to increase octane so you can run more boost. Methanol is what adds octane and is about 110 octane itself. It takes more octane to run more boost, so a higher concentration of meth vs water typically allows for more boost to be added. Many people only add 100% meth to increase octane, but adding water helps cool the intake air temperatures so the combination of both has extra benefits. However it’s the meth that changes your octane levels and is what prevents detonation at higher boost levels.I usually increase the water when I increase the boost.
