I have BMS meth kit with AEM nozzle. Used WW tank as meth tank.

I don't think it is worth the benefit. You shouldn't use meth while tracking anyway. No point in daily driving either.

I tried 50/50, 70/30, and now using 100% meth. You get 1 extra psi of boost for all the hassle. You can only benefit (probably ~30hp max) from it if you make a rolling race, that's all.

Go for e85 fuel instead and a custom flash with proper fuel map that goes with it. You'll make way more power.

P.S. Meth in WW tank makes me psychologically uncomfortable.
