Any of you guys running water/meth injection? Just looking to see what your tunes look like

I’m currently setup with a stage 2 snow performance kit, with a 10gph v2 Nozzel about 10inches from the throttle body. It’s on a progressive controller, injection starts at 9psi and is at full by 18psi and up, max boost is 23/24ps. In a 4th gear pull I get full boost by 3480rpm, I’m using the m-tune E85 maps as a base and so far this car loves it, 1st, 2nd, 3rd will spin when boost hits. I’m betting I can add another degree or two of timing without issue… I know playing with fire LOL. Here’s my timing map, I just realized I need to swap the 9.9psi column with the 6.9, somehow I swapped those

I use the Aquamist system, but it has it's own controller. Its claim to fame is their fast-acting valve that is controlled with a pulse-width signal, and a self-contained controller. My sense is that the engineers got wrapped up in the technical intrigue and that the tech doesn't necessarily translate to a better water injection system. In any event, I won't have cell-by-cell values I can share. For max boost, more/all water and less meth works better on knock in my car. Too much pure water, however, and you can start blowing out the spark and missing (at least with E85). So for me it's about finding the sweet spot between boost level, timing advance, water/meth ratio, and overall injection quantity. My efforts have been unscientific, so I won't pretend to know where that sweet spot really is.

something about being Mr White and meth tuning seems to ring a bell....

I knew there was more to the story... Heisenberg lives on as an engine builder.

it gets worse....My father was a nuclear physics (ex Cornell professor) that lived in Santa Fe. I know that area really well.....
