I play on Android and I only go online to get the daily bonus, but I noticed something in this routine. Specifically on the Le Mans circuit. Until a very recent upgrade, I played with the 919 at 94,5 PR, or something.
When I'm offline and get the best of the righter that leads into the first third of the Mulsanne straight (the longest one), I can hit 368-370. But when I'm online, the car can reach 376-378.

How the hell is that? And more importantly: why??
