Gas station gas
I have tried almost all the gas stations in my area and so far the only one I can trust for max boost ( 1 bar ) is marathon 93 oct. I can't tell any difference from 106 oct, which is also available at my local marathon station. Anyone notice anything similar or different.

Adding 100 or 106 to a tank of 91, 93 will bring the mixture up to the octane so that the engine will not be pulling timing.
While it is true you will not get the full benefits without a specific tune, the factory tune is optimize for the fuel of around 96-98 octane as measured (R+M)/2.
And "boost gauge readings" as a performance indicator are ill conceived IMO. You will see changes in timing advance not boost necessarily.
Finally it is absolutely false that an external boost controller is needed to see improvement with with increased octane fuel!

Ard, if you read my comment, I said, "feel" the difference by using the higher octane fuel. You may "see" timing differences in a data log, but at 1 bar on stock 16's you won't feel any more power. And this is what the OP stated already.
OF course you don't need a boost controller to add more power when a tune can handle that.
