How do you handle the orgination of the tuning bug?

I´m still not finished with re-downloading the tunes,caused the tuning by the tuning bug witch don´t get the right datas for the front of the car. I got so many cars, now I don´t know which car is right, which car is wrong.
And I don´t like to reload the tunes everytime I use the car. Deleting all the cars won´t help (thats no problem for me, I got enough cr to rebuy them), the tunes are not saved with the car. I didn´t find an option to delete all tunes at once. I even would start the game at point zero if this would help but I don´t know how and I think I can´t delete the data of the cloud.
Does anyone got an idea how to handle this?

(sorry for my english)

The only thing i believe you could do is start at your first car get in it and delete the old tune and download and install the new one right away. At least you will know where you started and stopped until you get them all finished. It’s gonna stink but my buddy’s in the same boat as many others are.

You could just redownload the tunes whenever you use a different car, and keep a record of the cars you’ve done so you don’t repeat them.

I would download manteomax spreadsheet and insert a couple of columns for cars owned and tunes redownloaded.

Google manteomax to find his spreadsheet.
