with a custom tune
Also, nobody can help with moisture buildup/water buildup in tanks. That's why you make sure to buy high octane from the busiest gas stations, as low volume gas stations high octane fuel sits for a long time (and if you run 94, or any of the 91 octane fuels with ethanol in them, SURPRISE, they absorb more water).
But even with all of that, your point is invalid, and is further invalidated (essentially, your invalidation has been cranked to -11) because of a custom tune done by who the hells knows who and the reasons of why your car needs it, completely rendering this discussion null and void.
If you didn't notice, modern cars are starting to come without fuel filters. That says something, and that something isn't that auto manufacturers are idiots.
