Dammit, I tried to simplify by talking about volume. Volume doesn't mean anything either, what the AFM is ACTUALLY doing is extrapolating moles. Moles are literally defined as # of molecules in a given volume. Moles NEVER change but pressure, volume and temperature do. As such, you are wrong. All that really matters in an internal combustion engine is the ratio of Oxygen atoms to gasoline atoms. If you improve efficiency anywhere in our intake setup, you will see FC at a lower manifold pressure.Spiv said:blk72t: you saw FCO at a lower pressure because of the 60 trim. Colder, denser air is means less volume (therefore less pressure) for the same fuel, and yes you see a degree of that with the improved intercooler, but more importaintly you see more of what's produced at the turbo making it to the manifold. If you look at either part alone you get an opposite answer, when you look at the whole picture you'll see lower FCO for a significantly more efficient turbo, or a more efficient IC with the same pressure drop, but when you're talking about a 3psi+ pressure drop difference it should result in a slightly higher FCO.
Point is, he shouldn't be seeing nearly as much boost at the manifold as he is.
