Aspects I like about the water injection are the cleaning properties and EGT/particulate reduction. Direct injected, EGR equiped engines can get carbon build up in the intakes very easily and the water injection helps keep things clean, as well as reduce peak cylinder pressures when extra fuel is being added. Direct measurements with the BT tool show good EGT reductions on the D.

You are running 70% water? Is there any advantage/harm in trying 100% methanol?
Also, my car is due for the EGR recall, programming update. Any feedback on whether this increases/decreases HP? I know half the owners have complained about mpg decreases.
I was looking at the new mixer diffuser they install during the recall, doesn't that thing look restrictive? Has anyone tried running without it?
