AndrewC1989 - Good questions. Reliability has been the same as stock as far as I can tell. Not enough long term mileage to discern if the tune has any impact on various systems.
For DEF consumption, I know the consumption is higher than stock, but haven't calculated the numbers. For me, I just pick up DEF from the VW dealership and fill up every oil change ~7,000 miles.
