what do you mean when you say way to rich at 14.7? that is the stoich afr that the car should read when not in pe.
regards the low timing down low, this doesnt suprise me as my ve and a few others i know knock a bit down low on the stock timing so it is nessacery for some to be pulled out.
Id be aiming for 12.6-12.8afr is these cars as they appear to like it alittle richer that some and dont really do anything more when pushed closer to 13afr.
the pe isnt to bad, you could make little adjustments for your desired afr but it aint bad as it is.
the values in the ve table dont look to bad either but every car is different and even another car with the exact same mods will require different levels of fueling. Best to get wideband in there and check over what its doing and make some adjustments to the ve if needed.
