Ok, not sure what I am going to do with this motor that i am currently rebuilding for my 87 Mr2. The idea was to possibly go with a turbo, however, I am completely stuck with the fuel system. As you could all guess from the title, I was looking at an Apex`i air/fuel controller. It says you can change injector duty + or - 50%. Also, with 16 point fuel correction, what does this mean? Through my entire rpm range, there are 16 places in which i may change how much fuel is injected? Will this be specific enough for a turbo running at about 8 to 10 psi, with about 300cc injectors? Thanks for all the help guys!
