Dubai rival event

The leaderboard is messed up. I was sitting about 2 seconds off the leader and just checked back. I’m now 11 seconds down. That struck me as odd so I checked out the leaders. All the cars show a P.I. of 472 but I noticed the person in 7th had a tune. Thought that was odd as I thought the event forced homologation. So I try to slap on the tune to make up some ground and nope not allowed. BECAUSE THE TUNE IS A 791 S CLASS. What the crap?
