Sorry don't have much experience with the MAF scaling but for your first question, I got a lot of knock running the 93 oct stage 1 tune with 93 octane fuel (also 10% ethanol). Now I am running 91oct tune with 93 oct fuel and have no problems with knock and honestly, the car feels much faster and smoother on the 91oct tune. The easiest solution would be to just data log using the 93 tune and see if it knocks because if you use the 94 fuel, that might be good enough.
