Fuel/air ratio
What does a stock evo run for air/fuel ratio? What should a approx. value should a evo run with intake, exhaust? My car is running from 14.8 ~ 15.1 or so.. Wondering if this is a normal value or is there something to worry about.. When it dips back to the lower 14 value kinda a stutter.

First of all are you asking about normal driving or Wide Open throttle acceleration?
Normal Driving = Closed Loop operations
WOT = Open loop operations
During normal driving the ECU is set to keep the a/f ratio around 14.7 , it usually hovers around that area. When you are accelerating in such conditions that put your car in open loop mode then the stock tune for an evo I believe is low 10's.
