As some of you might know California has some crappy gas. 91 octane is the highest at the pump unless you hit the 76 station that carries 100 octane. I have been advised to run a .8 bar spring instead of the 1.0 bar. (which I think is a waste of time and money)

So, my question is can I run this higher boost (1.0 bar) on 91 octane without damaging the engine?

I would think 91 is too low to run 1 bar. You would need to run 93 at least.

Unless you can monitor what your engine is doing I agree, but in the winter you should be good.
