piggy back system

what kinda of piggy back system would you go with ,,,,which is da best one to go with for my 94 GSR b18c jdm



thanks Lex

u only really need a piggyback fuel controller if u have some heavy upgrades to tune ur motor like big cams, nistrous, turbo or supercharger.

i have an Apex-i SAFC piggy back fuel controller.

and IF you have those, instead of piggy back, i hear the aem ems is good.

[how much did yu pay for yours and were can i get 1 ??


much apprecated Lex
