It shut off on me twice on my way home when it was in neutral coasting to a stop... not sure why... but it did. Might it be too rich now? Might go back sometime soon and go for a higher octane tune, not sure yet. Just going to see what this one does first and what kind of mileage I'm getting with it.

Bring it back if its stoped like that i can easily fix that just need a lil more iac duty cycle added to it and it will stop.
and of course like i said if you decide you wana run 93 octane no charge well strap it back down and advance the timing for the better go juice.
your millage by very nature MUST drop some you were over 17-1 air fuel at cruise with it untuned and your runing the correct 14-15 to one now and thats why you arent getting the lean codes now. however you might lose a slight bit of millage due to that
