Apexi AFC Neo Suitability

[najiru]

Hi guys,
 
I\'m new to rotary\'s and have just bought a \'95 FD. I\'ve been warned about the differences in octane between japan and the uk and have been looking at the Apexi AFC neo piggyback. I\'ll be looking at increasing power to a moderate extent in the future too and just wanted to ask if this is a suitable unit to use? I notice people tend to go for a full stand alone.
 
Any other advice would also be greatly appreciated.
 
Cheers, N
