Ontario (Canada) Gas vs Tuned Cars

For all my BM3 users where do you fill up gas based on your tune. Whats the best gas in Canada? Shell 91 with no ethanol or petro 94 with ethanol?

you'll have to try both and log it and see what's better. it may vary from station to station.

The ethanol is already factored into the 91 octane rating so 94 should be significantly higher octane. But as mentioned above the datalogs will tell. From what i have seen you will likely need to run the 91 map either way.
