D2 S8 Remap - worth it or not?

I suspected as much, thanks for your replies. I'll save the money for something more important.

I use V-Power all the time and there is a noticeable difference if I have to use another brand, and even then I'll only put enough of that in to get me to the next Shell station.

Tesco do a 99 but the flake keeps clogging up the fuel filter.
