For those of you water/meth heads out there, just how damaging is it or could it be to run a kit without a tune? I've researched this a little and seem to get mixed answers. I'm about to put a water/meth kit on a type S that's blown+HBP with a few other bolt-ons, and I'm wondering if I can run the kit for a few days with no engine mgt without damaging anything, and if so, what mix.

I would recommend not even using the kit with out some sort of management.

There will be too many factors that will come into play as in detonation, knock, misfire, just way too many variables to risk without proper management.

Talk to some engine guys, and make sure they aren't like non-official either I am talking certified tuners of some sort that have years of experience with water/meth injection.

Running water/meth w/o a tune will, if anything prevent knock etc, but is dependant upon what psi you set the meth kit to start spraying. If you set it too low, it may cause bogging and performance degradation by throwing too much moisture into the airflow. If you're running the hbp I think it's safe to set it at 3-4psi to start spraying.
Of course its best to get it tuned though so you ensure you're running optimally and can advance timing based on what the meth kit is capable of in terms of controlling detonation.
