um!!
You appear to be confusing using methanol in the WI system with using Methanol as a fuel, this would require an engine Specced to use it are you sure its not your pal thats on the meths.

To repeat----------
The Methanol is only injected when Charge air is over 40c & when boost is applied so it should not be working under normal circumstances if it does you have an Intercooler problem. On mine its only comes on under extended time on full throttle & when using 35+psi , you should not require this method of controlling the CA on anything other than very high Powered cars.
It cant make Power only you may lose less than with water or leaving the ECU to cut Power.
