water/meth injection your thoughts? and tech advice

[JET]

The AEM can control the meth setup, most pumps aren't progressive though, you would need to add more injectors that get turned on in sequence. I don't think you are going to see that big of a jump with meth, probably more like 3-4 octane. That depends on how big you jet it, but you can get too much in there too and start losing power. I would check out some of the Evo forums, they seem to use it quite a bit.
