On my TSI 4motion with DSG I got better MPG after the remap due to more aggressive timing and sure also because DSG engage earlier next gear due to increase torque
But cruising on flat highway at 100mph I also see better MPG and their the DSG does nothing as it is anyway in 7TH gear at about 2700rpm ( from what I remenber Could be 2800rpm). If you have a remap where extra power is mostly coming from boost then you will see worse or same mpg. If you have a remap were gain come more from agressive timing specialy at part throttle then you will see better MPG.
If you know what remap you want to buy ask them what is their timing from 1000 rpm to red line. Or ask somebody who already got it to log it with Vagcom. then you know if it got more agressive timing or just more boost
