Awhile back a friend of mine installed a Greddy profec spec B in my SR swapped 240, and its never really seemed right. I know nothing about these, and dont know where to start as far as tuning it. If someone could give me some help, or share your settings and setup I'd appreciate it. Also, if someone could tell me how its SUPPOSED to be installed, that would help. I'm starting to question its even installed right.

 

look up the wiring diagram for it, make sure everything is right. you can find a pdf manual download for it somewhere too im sure

 

everything looks right. Still need some advice with tuning this thing.
