Oh yea, I instantly gained about 1-2 mpg on the highway with the swap. At 70mph it's only turning about 1600

Not bad! Who reprogrammed your computer to a m6 program? I was thinking about sending mine to frost... I bet my 2.73s would turn about 1200 rpm at 70 in 6th. Lol

Yeah, I sent mine to Frost. He is really busy, so communication with him might not be quick if you needed to ask some questions, but he did a good job.
I wouldn't even try to run it on 2.73s. I would at least look for a used 10 bolt with some 4.10s until you can get an S60 if money is tight. My 3.23s really aren't fun to drive as it takes a lot more footwork to get the car moving with the tall gears. It's harder on the clutch running it like this and the engine bogs right off idle. I can't wait to get my 4.10s in and not have that soggy feeling anymore.

Tires good? Could have been spinning but it wasn't obvious/audible. Same dyno wifes car dynod 405, year after with fuel changes it dropped to 310. Made a fifth gear pull and numbers jumped to 397. Same thing with buddies c6z too.
