AEM strongly recommends that users never exceed a 50% methanol concentration when using any AEM Water Methanol system or component. All AEM water/methanol injection systems and components (pump, lines, fittings, filter, flow sensor, tank, and nozzles) are 100% chemically compatible with methanol. However, for safety reasons we strongly recommend that users never use more than a 50% methanol concentration in our systems. Methanol is a toxic and highly flammable chemical. 100% Methanol ignites easily and burns vigorously with an almost undetectable flame. Methanol can be absorbed through the skin and even small amounts can cause blindness or even death. Using this fluid at high pressures, without dilution, in an under-hood environment with nylon lines and push-to-connect fittings is very unsafe. The performance advantages of using greater than 50% methanol concentrations are small, if they exist at all. However, the safety issues are very real and far outweigh any perceived benefit of running high concentrations of methanol.

My advice is to ignore AEM instructions as that is for beginners that do not have another source of information for a more professional style setup or suggestions, which you have here in this thread., read through the tread and use what you find and implement that to your setup . Multiple locations that all work well some locations better then others , but regardless of location which is going to be a preference for your specific setup, using the correct amount, using pure meth and using quality material is what we all have in common which is why we all see results in some form. Do not use window washer fluid, that's a cheap alternative, it is not 50/50 and the dye will actually bond and cake in some areas destroying sensors. Use pure meth. Or at minimum use a mix you personally can make use distilled water. But know that water will not add power and will slow you down vs pure meth. For your setup I just don't know what's best , as far as , location, amount of meth, how many nozzle etc because you have a v6 . Perhaps someone with a v6 has tested some locations. Perhaps start a thread asking if anyone has experience with meth in your platform. As far as a progessive controller. for the m157 I find it absolutely useless. The difference from 5-30 psi is literally at the block of an eye so it will just cancel out any progressive settings. It's best to pick a psi you want it to turn on fully during WOT.
