Has anyone ever added octane boost to 93 octane and found an increase in power etc.

93 octane would be "optimum" for maximum performance, however it not required. The DME programing will handle just about any gas you can find by altering various settings. You will be fine on 91 octane.

For some reason we can get 94 octane in BC, at Chevron. When I did a trip thru the Rockies a few years ago, I found they didn't have it in Alberta. Sounds like not in Ont either. Go figure.

There's several stations here in ONT that carry 94...
Here in Guelph the PetroCan station downtown carries 94 which is my usual fill up station
Most of the Shell stations also carry 93 in this neck of the woods so all good here...
I do keep a bottle of octane booster in the car just in case I get caught filling 89 or 91 somewhere
in a pinch.... but so far I haven't used it yet.
