Tuning: EGTs after adding water injection

[Andrew]

Okay, here are some of the relevant parameters.

Engine: Stock WRX 2.0L
Turbo: SR30
Intercooler: Stock
Water injection point: ~5psi

Hotrod, your comment about the sweet spot got met thinking, so I went back and checked the compressor map that I have. Sure enough, at higher rpms, the turbo is running at a lower efficiency, so I lowered boost from ~17.5 to 16psi from 5500 and up. My max boost is about 18psi in the 4000-5000 rpm range.

I just made the change this morning, so I'll drive it a little and see how things have changed. I'll also post a log.
