Default Is this too LEAN? dyno a/f

dyno for my stock JDM b18c1

The guy who was operating the dyno commented.. "oh wow thats lean"


Is this a normal a/f reading for this motor stock, or is it truly running leaner then it should be?


Also how does the HP/TQ look? up to par? (156hp 118tq)

Looks o.k. to me after 4,000 rpm. 4,000-5,800 may be a little too rich. You could richen it up a little from 6-8,000, but 13.8/1 is not excessive. All motor likes to be a little fatter (13.2-13.5), but you should be o.k.

yeah it's not too bad,
might be kinda aggressive,

but probly makes good power,
I don't like how it's all rich down low though in comparison,
I mean, isn't lowend already weak enough? Whats the point of having it
make less power and take more gas?
