Starved for fuel/stalling
I noticed more recently my 919 likes to stall/stutter when hard braking from a higher speed, and I'm guessing it's because the fuel sloshes to the front. I have a normal range of 130 miles, but this has been occuring around 70-80 miles...which might be another problem of getting low MPG's. In general, this only happens with half tank or less, and when hard braking to a stop from highway speeds. I replaced the FPR earlier this year so I highly doubt that's the issue.
1. Stalls when braking with lower fuel (no light on)
2. Low MPG recently (70-90 miles instead of 130)
