hello anyone ever alive here anymore??????

 

I'd like to know too. I have a basic stock b20z, sk2 manifold, itr manifold, cat, fpr. I've been getting pretty bad gas mileage (20-24). Fuel pressure was like initially 45, then 42, recently I adjusted to 38 at idle. I don't have a dyno to go by, but it feels better all around at the last setting, powerwise.
