AFRs after injecting water.

[themadscientist]

I just tuned my first WI WRX.
Tuned AFR is 12.5-12.8:1 I was able to add 4 points of timing, and the TD04 is blowing 20psi in the mid range tapering to ~16psi at redline without det. Next week I should have it on a dyno to try and lean it out even further and see if it makes more power.
