Any more commentary on the 3rd row for GMT900s?
I think I’ll go for whichever I can get in better shape between the 6.0L and the 8.1L for GMT800. Did some reading at lunch today about improving 8.1L MPG and there’s some folks out there both with HPTuners (which I have) and EFI-Live that have testimonials on forums that they can get the 8.1L up to around 14.5 on the highway with stuff and 10.5 with a trailer. Not looked for 6.0L tunes to do the same so it might have similar gains, community for it’s bigger.
Did they sort out the DOD/AFM on the later 6.2Ls?
