I don't get this. Yes, I have standard engine mapping in garage and change to fast on track. However, after about 20 or 30 restarts, whatever ghost I'm normally ahead of at the start of a circuit leading into turn 1 starts to get very quickly ahead of me, no matter how consistently I gear change from restart to restart. The car is definitely getting slower, as though it flips back to standard engine mapping. So I have to exit the game and load it up again before I'm able to be ahead of the ghost for another finite amount of restarts. I also always do my quick wheel calibration before loading. Can this be the DFGT or the game? No amount of changing back to standard and then back to fast makes a difference, nor does just going to the garage to reload my setup with standard mapping.
