MAF tuning for turbo
I just swapped a 6.0 in place of my 4.8 and kept the same turbo system. Can i use the same values from my MAF tables i had with the 4.8 or will it be completely different for the 6.0? Thanks

You'll be just fine running the stock MAF calibration table. Compare a 4.8L tune to a 6.0L tune (of the same year), and you'll see that the MAF calibration is identical.
The MAF measures incoming air, completely independent of engine size. 300g/sec of incoming air is 300g/sec, regardless of whether its on a 4.8L at 6000rpms or a 6.0L at 3/4 throttle at 4500. The important piece of the puzzle to have correct with a change of this type is your injector flow rate, as MAF calibration relies heavily on IFR to provide accurate fueling.
With a change from 4.8 to 6.0, the VE will definitely need to be scaled up a bit. Cranking VE, Afterstart enrichment, idle airflow and a number of other tables will also need to be changed. You'd be best off taking a stock 6.0L tune and startign your re-tuning with it.
