[DOHCtor]

Ok... here are the results... the test was done going uphill on a specific hill at WOT in ''Drive'' and in similar conditions... Meteo, temperature, wind, etc...

The car seems torquier but not so much... (It's still stock!) it looses less speed going uphill when not at WOT and it gains a little more at WOT!!

I think that to make good use of premium fuels in a fit, you have to completely empty the tank of 87 octane, fill up with premium and then reset the PCM... It did worked for me as we can see...
