Default high octane fuel question

hi guys,

I moved my H3 to Europe, and finally got it licensed here (needed lights modifications and other stuff). anyway, back in Cali I used 87 octane fuel (or was it 86?) which is recommended for H3; here the lowest grade is 95 octane - do I need to reprogram the car computer, or can just let it go? I don't see any diference in engine peerformance...no rough running, idle rpm is same as well....

thanks for advice
