So I'm from Toronto and I'm planning on tuning my car using MHD. Reading through this forum, I've realized that Canadian fuel isn't as good as it is in the states.

For Toronto specifically, have you guys been able to run stage 1 tunes using 91 oct without any knocking issues? Or did you have to use a more conservative map like ACN, to avoid engine knock when tuning? Costco gas is the most convenient for me, so that's very likely the type of gas I would be using.

I just run a 91 map and only fill up with 94. This is what most people I talk to do as well.

Have you had any knocking issues, or any other issues due to our gas being of poorer quality than in the states?

Edit: Also, do you think I would have issues using Costco 91 in Toronto, it's in a really convenient location for me.

I wouldn't recommend using Costco 91. I use to run Shell 91 and when I went Stage 1 91 Octane I started experiencing some knock which stopped when I switched over to Petro 94

Thank you for the advice, I wanted some real world experiences on this topic.
