fule cut off is when????

[ddmcse]

you havent hit it yet if you have to ask

the engine cuts out for a fraction of a second . the check engine light comes on for a short time then thats it . you can hit FCO at very low speeds or very high speeds it all depends on your set up . outside temp and humidity have a great effect . along with the position of the sun and the moon .. j/k about the moon and sun
in general it's around 10 lbs of boost . i use a gauge installed in the intake manifold (upper) in addition to the stock gauge
