this thing APEXi SAFC S-AFC V.2
what does it do ? and whats it used for , is it worth it , or just another boys toys too much money around thing

 

apexi fuel cut defencer , used in conjunction with a boost upgrade (manual) or electronic adjustable boost.

 

safc 2 has real time knocklink display,12 point fuel correction and allows fuel enrichment of 50%over manufacturers spec and looks cool, also has 2 presets to go wth a boost controler (high boost or low boost)

hope this helps
