Anyone with WB02 on stock ecu ???

What are you reading for you AFRs at cruise and at full throttle?

I am seeing fluctuating between 14.2 and 15.0 at cruise and at full throttle above 4.5k it is going 13.5ish. Just curious as I am going to smog it tomorrow and its been sort of gutless, but maybe its just the 3.0" exhaust.

Same(ish) here. 14.2 - 15.5 Kinda odd that it bounces so much. I thought maybe something weird was going on. On the other cars I've had it on it was maybe 14.4 - 14.9 at cruise.
