I just purchased a 1.4L turbocharged vehicle that is tuned at the factory for 87 octane, but during the summer, will pull timing even on 93 due to knock. I am not looking for “more power”, but simply looking to not have timing pulled. I understand that 87 and performance don't mix, but the wife may be driving the car, so I want 87 as the baseline if she fills up.
I am considering the following five choices. I own the necessary parts for the water/meth kit, as well as enough meth to keep the kit fed for 2 years. |

All water injection that actually does something, i.e. provides a high enough water to fuel ratio, needs a retune.
Without adapted ignition timing, it will actually reduce power. You could add a FMIC spray as an alternative. This won’t require a retune. Flexfuel is also a good choice. |
