Does anybody see any benefit using high octane fuel for example Shell V Power 99 Over regular for example 95 Tesco Diesel with a tuning box fitted or with a remap?

I have a DTUK on my 535d 313ps and it is 2 years old and has done 22,000 miles. Im just wondering whether i should remove the tuning box and sell it and get it remapped to 360 bhp & 700nm or just keep the tuning box on.

Thanks
