Did you not read???
With a proper FMIC and a decent fuel you don’t need methanol… You can go wrong as things can fail. It’s one more thing in the setup to make things more complicated.
Garys pump has failed on more than one occasion, he knew because he is ever mindful of things and has designed his own safety measures into his kit. I can see most people not noticing this during a run and well KABOOOOOOOM. Making a pull on a car that has been tuned for methanol on no methanol = a bad scene.
Keep it simple.
