I have the same things you do, except I have a hi-flow cat instead of an intercooler (soon to change) and my s-afc is more than enough. Before when I had the stock cat, I dyno'd in at 9.0 fuel-air ratio from 3500-7000 rpm (i also had the k&n replacement instead of my blitz sus filter). At that point it's actually too rich, which explains why I only had 234.9 hp & 229.4 lb/ft

aight... well, I'm running the old skool one and it's kinda hard for me to tune anything when I think my O2 sensors are screwy now.. air/fuel gauge stayed at lean..... how many O2 sensors does a Fd has anyways?
