It shouldn't be a problem. Increasing octane is nessasary for advanced timing and higher compression ratios. The chip will change the timing. Do not try to run that setting with lower octane fuel unless you want your engine damaged.
yes it will handle it,running higher octane fuel doesn't really create that much more heat,it just burns a lot smoother than regular fuel does,it wont hurt it none at all to run higher octane fuel in it,good luck.
