Check your bike acceleration Acae_Y against other ghosts
I noticed the unnatural speed the other day whilst racing Acae_Y on Deadwood Valley, try for yourself he is currently 2nd place on the track. Without modifications this acceleration is impossible to achieve, I think it is just the acceleration but could also be the handling, grip and top speed. It is clearly not normal.
To Acae_Y - If indeed this acceleration increase isn't intentional by you then check your device as there is definitely something wrong. You can check to see if your acceleration is correct by simply racing a ghost on a track with a start that is a simple press of the accelerator. For example race someone in the top 10 on Deadwood Valley and watch your bike pull away at the start.
I hope you get this sorted so your rank isn't inflated and in turn keeps some sort of integrity to the leaderboard. This is the route cause of our problems in the first place, if there were no people cheating then RedLynx would have an easy time keeping the leaderboards in order. On the other hand if this is due to a devices performance on the game then the problem is just compounded even more.
