Problems with shared tunes

One of my friends is one of best tuners for drag racing. But there is some type of problem and it’s hard to explain. He will tell me he’s sharing a new leaderboard tune to drive. So ill go to his tuning setups download the new tune and try it out. This is the part i cant figure whats going on with the tune. The camber changes along with the gearing and the suspension, the tune does not work. So i decided to delete the tune in the car and the shared tune i got from my friend, i go back to his shared tunes to redownload it. Now i go to free play start running the tune and first run i hit number 5. But when before the tune was changed somehow by its self. I am not the only one experencing this problem either. Please post a reply if its happened to you.

I have had a slightly different problem. Sometimes I will load a tune and it does not get the car to the exact pi. My solution is simply to reload the tune and it fixes it. I would try just loading the tune twice.
