How much water do you use?
I like to use about 2 gallons of water to each gallon of fuel burned. But on long road trips I use closer to 1 gallon of water to 1 gallon of fuel because I just cant carry enough water.
If you start the water injection at 5psi then I bet its hardly ever on.
I run my water all the time when I am at speed.
Before water injection I could never get over 20mpg towing, now with water I consistantly hit 20mpg all the time no problem. Last road trip I had one tank under 20mpg, before water I would get 18-19 most of the time and maybe see one tank over 20mpg.
Last road trip the suburban consumed over 200 gallons of water.
I still plan on running water a 03 duramax intercooler.
EDIT: sold the D-max intercooler and went with a 3 inch in/out universal fit 31x19 inch unit.
