How's the oil consumption?

And it's a turd compared to what?

Take it to a track and get a time out of it.

Bad O2s? Bad tune? A little of both?

doesnt burn any oil. Ive drove a handfull of LS1 cars with bolt ons/stall/gears and this thing feel more like a 3.8 than a modded LS1.

leaning towards something in the tune. trying to get that checked out this week then we'll go from there.
