Just a quick recap:

1. The HFS-3 is triggered at quite low IDC%.
2. The engine is receiving water/meths before spooling?
3. As the system tracks IDC the tuner is able to tune the partial throttle area.
4. This is encouraging as most tuners would only tune at WOT with boost based systems.
5. The HFS-3 appeared to faitthfully deliving the injectant over very wide operating range. It is good to know the system is performing consistantly as designed.
6. It would be interesting to know if the fluid consumpion at the dyno improve with daily driving condition, please update.

I would be interest to see what will happen when you start to increase meth %.
