However, getting to the point of = your=20 question - not to worry. It has no significant effect on the = Air/Fuel=20 mixture.

OK, I guess I can see that. =20

Next silly question- If temp is so important, = will it=20 matter where the injectors are? Imagine having the stock primaries = in the=20 block, along with secondaries in the TB. I imagine that the = fuel=20 atomization lowers the temp, so will the temp change along the pipe as = new=20 injectors are encountered?
