I have a 2000 civic EX with a t3/t4oe .48 ar. I have 310 injectors, 255? walboro fuel pump, 3 inch exhaust with 2.5 inch charge pipes.

So... i know basically know nothing about tuning and what i should do, my vafc settings a friend of mine that i'm no longer in touch with set it up for me and it's run fine for 5 years on a stock motor.

Still people keep telling me it'll run even better with some real tuning and i have access to a wideband o2... What should i be aiming to do? Is there some optimal air/fuel ratio i should be shooting for?

Thanks in advance
