Sup ya. So got my FC running more proper, fixed a few things here and there. Added a wideband, car came wired up with a non adjustable Fcon ecu. So my wideband reads 10.7 on idle and stays around 10.5 up to 6k rpm and goes as low as 8.7ish. so yeah, running really rich. I currently have a knights sports hybrid turbo, greddy top mount, 3in down pipe, and street port. What can I do to make it run not soo rich till I can afford a adaptronic. I was thinking of installing an adjustable FPR and lean it out a bit, would that work? Or what do you guys recommend, thanks in advance!
