Dangers of Running Rich, 3sgte owners Options

[jgreening]

Well, ten days into ownership of the 3sgte and I can safely confirm what everyone else has said over and over....these engines run very rich. I have read many posts about this and about the fact that Toyota made it this way to avoid lean conditions. However, I would imagine that running an overly rich condition cannot be good for the engine over time either. I am wondering whether for engine longevity and reliability purposes, us 3sgte owners should take action either through an S-AFC or stand alone to lean out the A/F ratio. Obviously, we can see some horsepower gains from doing so but I am particularly interested in responses dealing with engine life.

Walbro a NO NO!

After reading through this <very long> article(s) I dont kno if im putting in this walbro because it seems to mess around with the fuel rail and cause pressure drop. This can lead to running rich in some cylinders, destroying them.
