my alloytec 190 AWD adventra does about the same as my LS1 sedan... 12.5 ish around town, high 9s on freeway. should be able to do better than that in a sedan.

my narrowbands swing about, the widebands I read in lambda.
12.5 gee I just checked mine this arvo it's 16.2 and I drive it very easy bevause I know it's a thirsty bugger.
It's an 05 6 speed crewman. Not sure if it's in need of a major service or a tune surely it's not meant to be that heavy on juice. And it has bugger all go too. Really lacks power should put my wideband on it one day to see.
If it hasn't had a tune it's definitely worth getting one, my old VXSS was great on fuel and it was auto, it used as much as my V6 sidi does but I use to flog the V8

Curious when did Holden turn off lean burn?
