Had my f80 on the track for the very first time last week, and did experience the fuel starvation issue. Accelerating out of turn 2 @ VIR doing about 90ish with a GT3RS right on my ass. Car went limp mode and I was almost run over by said GT3RS. Good thing the guy had good reflexes. I had maybe 1/3 of a tank when it went limp, had to motor all the way around the track a good 3 miles on a hot track going about 40 so I could pit in, clear codes, refuel (and change my underwear
). . After that, I started filling the tank after every session. Event was with Chin, which typically runs long sessions. I burned more than half a tank during the morning 40 minute runs. Pulled 1.30 max Gs on NT01s.
So yeah, I think the issue is VERY real, and VERY dangerous. Never once had this issue with the e92.
