LS1 goodies.

[Ross Myers]

Hi all,

Well now the LS1 is available in our 'family' cars here in Oz, I took some
interest.
Given the U.S folks have had these for a while now some of you may be able
to fill me in on something that is puzzling me.
Holden's stated Fuel Economy figures are not much worse than the 3800 of a
few years back, how?. Are the PCM's running these LS1's a new generation?,
do they run very lean at cruise?.

Thanks

Ross Myers
